Beginner's guide

So you're getting into caving

Underground is a different world — dark, wet, and unforgiving of shortcuts. Recreational caving doesn't require mountaineering experience or a massive budget. A certified helmet, three light sources, and a pair of coveralls get you into most beginner caves. Here's exactly what you need — and why the gear list is shorter than you might expect.

The 60-second version

If you only buy 3 things to start:

  1. Petzl Boreo Helmet — The certified caving helmet every NSS instructor recommends. Get this before your first trip, no exceptions.
  2. Petzl Actik Core Headlamp — 600 lumens, USB rechargeable, clips to the Boreo natively. Your primary light source.
  3. Dickies Men's Coverall — Caves destroy clothing. Dickies coveralls are the community answer: cheap, durable, at any hardware store.
Budget total
$200
Typical total
$350
A certified helmet, primary lamp, backup lights, coveralls, kneepads, and gloves run about $200 at the budget end. Good-quality picks run closer to $350. NSS grotto membership ($40-60/year) gets you guided trips and gear loans — often free for your first outing.

Before you buy anything

A few things worth knowing first

Join your local NSS grotto before buying anything else. The National Speleological Society's grotto system connects you with experienced cavers who will lend you gear for your first few trips, show you local caves, and save you from buying the wrong things. Find yours at grottos.nss.org.

Don't cave alone and don't explore unfamiliar caves without someone who knows them. This isn't overly cautious — it's how the caving community structures itself. The same NSS grotto that lends you gear will invite you on your first guided trip.

The three-light rule is non-negotiable: every caver carries three independent light sources. Not two. In complete underground darkness, losing your only light is a very different situation from losing one of three. Your helmet lamp is one. Carry two more.

The gear

What you actually need

Helmet

Your helmet is the first thing you buy and the one item you cannot improvise. Bike and ski helmets don't protect the right parts of your head underground — you need a helmet certified to UIAA or EN12492 standards that handles overhead rock strikes. The secondary requirement: a headlamp bracket. Almost every certified caving and climbing helmet has one; almost no uncertified helmet does. Budget $50–140 for your first helmet, and get the Petzl Boreo unless you have a strong reason not to.

Helmet — what's the difference?

A few common shapes, each making a different trade.

Open-Face / Foam-Lined

Light and affordable. The standard beginner pick.

Cert
UIAA/CE
Liner
EPS foam
Weight
~300g

Best for First-time cavers, dry and semi-wet caves

Tradeoff Foam compresses over time; less protective after 3–5 years of heavy use

Suspension / Full-Shell

Rigid shell with suspension harness. Better for prolonged crawls.

Cert
UIAA/CE
Liner
Suspension cradle
Weight
~390g

Best for Frequent cavers, multi-hour trips, wet and muddy caves

Tradeoff Heavier and more expensive; harness needs occasional adjustment

Best starter
Petzl

Petzl Boreo Helmet

$$

The Boreo is the go-to entry-level caving helmet in the US — UIAA and CE EN12492 certified, comfortable foam liner, and the headlamp bracket fits every major caving lamp including the Actik Core below. It sits squarely in the sweet spot between 'budget climbing helmet' and 'professional survey helmet.' Buy this first.

What we like

  • UIAA and CE certified — meets the standard caving and climbing gyms require
  • Native Petzl headlamp bracket accepts every Petzl caving lamp
  • Comfortable foam liner stays put on multi-hour trips

What to know

  • Runs small — order one size up if between sizes
  • No ventilation slots — can feel warm on physically intense trips
Budget pick
Black Diamond

Black Diamond Half Dome Helmet

$

The budget entry. Meets UIAA and CE standards and will protect your head, but it was designed for rock climbing — the vent slots let in more mud and water than a dedicated caving helmet. Most headlamp accessories clip to it fine. Good for a first cave trip while you decide if caving sticks.

What we like

  • Meets UIAA and CE standards at a budget price
  • Widely stocked — most outdoor retailers carry it

What to know

  • Vent slots fill with mud in crawls — not ideal for tight wet caves
  • Headlamp bracket fitment varies — test before the trip
Upgrade pick
Petzl

Petzl Vertex Vent Helmet

$$$

The step up serious cavers make after their first year. Full suspension cradle, maximum ventilation for demanding trips, and the helmet worn by cave survey teams. Noticeably more comfortable on four-plus-hour trips than the Boreo, and the native Petzl bracket accepts every lamp in the lineup.

What we like

  • Full suspension cradle — more comfortable on long trips than foam-lined helmets
  • Worn by cave survey teams and rescue volunteers — proven field durability

What to know

  • Premium price — overkill if you're caving once a month
  • Heavier than foam-lined helmets by about 100g

Headlamps

Three lights. Every time. Not two, not 'my phone has a flashlight.' In complete underground darkness, losing your only light turns a routine trip into an emergency. Your helmet lamp is your primary; pack two more. The secondary can be a backup headlamp or handheld; the tertiary is your insurance policy — something cheap, light, buried in the bottom of your pack. Total cost for all three: $100–150.

Best starter
Petzl

Petzl Actik Core Headlamp

$$

600 lumens, a USB-rechargeable battery with AAA alkaline fallback, and a bracket that clips natively to the Petzl Boreo. This is the lamp most NSS grotto members will point you toward as a first caving-specific purchase. Red mode protects other cavers' night adaptation during group navigation.

What we like

  • USB rechargeable — no disposable AAAs burning through your primary light
  • Clips natively to Petzl caving helmets, no adapter needed
  • Red mode preserves group night adaptation during navigation

What to know

  • Battery drains faster in cold — carry AAA backup batteries below 40°F
  • 600 lumens covers most caving; serious cavers may want more throw
Upgrade pick
Black Diamond

Black Diamond Spot 400 Headlamp

$$

The upgrade for cavers who want a tighter spot beam for reading cave topography at distance. IP67 waterproof rating that handles submersion, and a PowerTap brightness control on the rear panel that lets you manage battery without cycling through menus. A solid primary for serious cave trips.

What we like

  • IP67 rated — genuinely submersible for stream caves and wet passages
  • PowerTap rear control adjusts brightness without menu cycling

What to know

  • AAA only — no USB recharge, disposables cost adds up
  • Heavier than Petzl options when loaded with fresh alkalines
Specialty pick
Princeton Tec

Princeton Tec Byte LED Headlamp

$

Your emergency third light. Tiny, under $25, runs on AAA batteries, and decades-proven in the caving community as the tertiary you keep clipped to your helmet strap or sealed in a ziplock at the bottom of your pack. You may never need it — but underground, that one time matters.

What we like

  • Under $20 — cheap enough to carry three lights total without guilt
  • Decades-proven reliability as the caving community's tertiary pick

What to know

  • 70 lumens only — emergency egress, not comfortable navigation
  • Not a helmet mount — handheld or strap-clip use only

Coveralls

Caves destroy clothing. Sharp limestone, mud, and crawling put holes in anything thin within a single trip. The caving community's beginner answer is Dickies work coveralls from the hardware store: cheap, durable, and expendable enough that you don't mind the wear. Layer a base layer underneath for temperature management — cotton is dangerous when wet in cold caves, so go merino wool or synthetic.

Best starter
Dickies

Dickies Men's Coverall

$

This is the honest answer to every 'what should I wear?' question in every NSS beginner guide. Buy one size up to fit over a base layer, wear it over everything, and don't worry about it coming back clean. When it wears through, buy another. Available at any hardware store for $35-45.

What we like

  • The community standard — what NSS instructors actually recommend to beginners
  • Durable cotton duck fabric outlasts thin synthetics on limestone crawls
  • Available at any hardware store — easy to replace or size locally

What to know

  • Cotton traps moisture in cold caves — layer merino or synthetic underneath
  • Heavy when completely wet — not ideal for stream or submersion caves
Specialty pick
Minus33

Minus33 Merino Wool 705 Midweight Crew

$$$

Your base layer under the coveralls matters as much as the coveralls themselves. Cave temperatures in the US range from 38°F (Appalachian ridge caves) to 65°F (southern limestone systems). Merino wool manages that range, keeps you warm when damp, and doesn't smell after repeated trips. One merino top and bottom is the correct layering system for most caves.

What we like

  • Warm when damp — won't risk hypothermia if you get wet in cold caves
  • Odor-resistant: wears multiple trips before needing a wash

What to know

  • Slower to dry than synthetic — avoid for water-heavy caves
  • More expensive than synthetics — $80–100 for a top and bottom set

Kneepads

You will crawl. Not gently — through tight limestone slots, on gravel, over wet rock. Beginner-friendly caves routinely include extended crawl passages lasting 20–40 minutes. Thin athletic kneepads won't survive the first trip. You need construction-grade kneepads with gel cups and reinforced outer shells. This is the piece of gear cavers most often wish they'd bought before their first trip rather than after.

Best starter
NoCry

NoCry Professional Knee Pads

$$

The construction-grade benchmark for caving beginners. Thick gel cups, hard outer shell, and articulated straps that don't slip while you crawl — the specific failure mode of cheaper kneepads. Used daily by flooring contractors and tile setters, which is exactly the kind of sustained crawling caving demands.

What we like

  • Hard outer shell holds up on sharp limestone where gel-only pads fail
  • Articulated straps stay in place through extended crawls
  • Contractor-proven durability — not a gym kneepad repackaged for cavers

What to know

  • Bulkier than slim athletic kneepads — tight squeezes can feel the difference
  • Straps require re-tightening mid-trip on very long crawls
Budget pick
ToughBuilt

ToughBuilt GelFit Knee Pads

$

A genuine budget option that holds up better than most. The gel cups are softer than NoCry's hard shell but straps are comparable, and you won't feel cheated on your first few trips while deciding if caving is your thing.

What we like

  • Budget price — right call if you're not yet sure caving will stick
  • Gel cups comfortable on long kneeling sessions without a hard edge

What to know

  • Gel exterior wears through faster on rough limestone than hard-shell options
  • Straps less robust — may need replacing after a season of regular caving
Upgrade pick
Portwest

Portwest KP40 Ultimate Knee Pads

$$

When you're doing regular, serious crawling — multi-hour trips through tight limestone systems — budget gel pads wear through fast. Portwest's hard outer shell is designed for sustained industrial use and outlasts budget options three-to-one on abrasive surfaces. The upgrade most cavers make after six months.

What we like

  • Industrial hard shell outlasts gel pads three-to-one on abrasive limestone
  • Low-profile design threads through tight squeezes better than bulky options

What to know

  • Hard shell less comfortable on smoother rock or flat stone floors
  • Slightly harder to get on and off with gloved hands

Gloves

Cave rock is sharp. Limestone, sandstone, and basalt have edges you won't see until your hand is on them. Gloves do two things: protect your hands from cuts and give you grip on wet rock. The caving community's preference is leather work gloves — cheap, tough, and grippy when wet. Upgrade to cut-resistant tactical gloves once you're caving more than once a month.

Best starter
Wells Lamont

Wells Lamont 1133L Leather Work Gloves

$

Leather work gloves are what the caving community has recommended for decades — tough enough for limestone crawls, grippy when wet, and cheap enough to replace when they wear through. Wells Lamont's 1166 series is a well-made leather work glove available everywhere. Fit them snug so you don't lose them in a tight passage.

What we like

  • The community standard — what most NSS cavers recommend to first-timers
  • Natural leather grip improves slightly damp — handles wet rock well
  • Cheap enough to replace annually without regret

What to know

  • Stiffens in very cold conditions — warm up before rope work
  • No cut-resistant rating — fine for general caving, not for very sharp rock
Upgrade pick
Mechanix Wear

Mechanix Wear M-Pact Gloves

$$

The tactical glove cavers move to once they're doing regular cave work. TPR knuckle protection, padded palm, and enough dexterity to operate headlamp controls without removing them. More expensive than leather work gloves but lasts two to three times as long. The right answer for frequent cavers.

What we like

  • TPR knuckle protection handles the hits leather doesn't guard against
  • Enough dexterity to operate headlamp controls without removing them

What to know

  • Synthetic grip less effective than leather on very wet surfaces
  • More expensive — overkill for cavers who can replace leather annually
Specialty pick
Outdoor Research

Outdoor Research Merino 150 Sensor Gloves

$$

Caves in the Appalachians, Rockies, and Pacific Northwest often run 38–45°F. At those temperatures, bare leather gloves won't keep your hands functional for navigation or rope work. These thin merino-blend liners layer under your main gloves or work alone in moderately cold caves. Touchscreen-compatible tips matter on the approach.

What we like

  • Merino-blend keeps hands warm in 38–45°F cave temperatures
  • Touchscreen compatible — useful for approach navigation on your phone

What to know

  • Too thin for abrasive limestone crawling on their own
  • Merino liner can pill after repeated use in rough caves

Your first month of caving

Most people who want to try caving don't know where to start. Here's the actual pathway — from your first show cave to your first wild cave trip with a grotto — and what to expect at each step.

Save your money

What you don't need yet

Beginners get pressured to buy a lot of stuff that doesn't help them play better. Here's what we'd skip on day one.

  • Vertical gear (rope, descender, ascender) — Vertical caving requires formal training and a mentor before any gear purchase. It's a natural second-year progression, but not something beginners should approach without guided instruction first.
  • Wetsuit or drysuit — Only for stream caves and sump systems — specialized environments that beginners shouldn't attempt solo. Cave diving is an entirely separate discipline with its own certification path.
  • Dedicated caving suit — A proper caving-specific jumpsuit ($100–300) is worth it after your first year of regular caving. Dickies coveralls from the hardware store do the same job for $40.
  • Survey equipment (compass, DistoX, notebooks) — Tools for mapping unmapped cave passages — advanced grotto work, not beginner territory. Join a survey team after you've gotten the basics down.
  • High-lumen technical lamp (Lupine, Scurion) — 1000+ lumen lamps are for survey teams navigating large cave systems. The Petzl Actik Core handles 95% of beginner trips without issue.
  • Knee-high rubber boots — Gum boots are useful in muddy or standing-water caves, but your first few trips likely won't need them. Wear what you'd wear hiking and upgrade when the cave demands it.

FAQ

Common questions

What's the difference between caving and spelunking?

Nothing meaningful — spelunking is the informal American term, caving is the preferred term in the organized community (NSS). 'Spelunker' has acquired a slightly pejorative connotation among experienced cavers (implying someone who goes without proper gear or training), but it's not a serious distinction. Use whichever word you want.

Do I need experience to start caving?

Not technical experience, but you should go with someone who knows the specific cave on your first trips. The NSS grotto system is the established pathway — they run guided beginner trips with experienced leaders. Going alone into an unknown cave is the scenario that fills the NSS's annual American Caving Accidents report.

What is the three-light rule?

Every caver carries three independent light sources at all times. In complete underground darkness, losing your only light is an emergency. Your helmet lamp is one source; carry two more — a secondary headlamp or handheld light, and a small tertiary light tucked in your pack. This is why the headlamps section recommends three separate purchases.

How much does it cost to start caving?

Gear runs $200–350 for a solid beginner setup: certified helmet (~$70), primary headlamp (~$60), backup lights (~$35), coveralls (~$40), kneepads (~$30), gloves (~$15). NSS grotto membership is $40–60/year and usually gets you guided trips and gear loans — ask before buying everything at once.

Are all caves the same temperature?

No — cave temperature roughly tracks the average annual surface temperature of the region. Southern US caves run 55–65°F; Appalachian and Midwest caves run 50–58°F; Rockies and Pacific Northwest caves can run 38–48°F. Dress for the cave's temperature, not the weather outside.

Is caving claustrophobic?

Some passages are, some aren't. Most beginner caves have a mix of open rooms and tight crawls. If you're genuinely claustrophobic, mention it to your grotto leader before the trip — they know which routes to avoid and can make sure you never feel trapped. Most people who think they're claustrophobic find it manageable with an experienced leader and a known exit.

Should I visit a commercial show cave first?

Yes, and it's a great idea. Lit, guided show caves (Mammoth Cave, Carlsbad Caverns, Luray Caverns) are a zero-risk way to see if you like being underground before spending on gear. Going from a show cave to a wild cave with an NSS grotto is the most common beginner pathway.
