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.
