Spelunking Caving Equipment

question about cave exploring (spelunking)?
ok i hve a couple questions about cave exploring cuse i hve nvr been nd would love to. my friends nd i were talking about going. we want the caves ya know were u have to do repelling nd stuff kinda like in the move the descent. ok my questions r:
1.) is there a website im like how do i found out were some caves r in my area and is it graded by difficulty?
2.) what equipment do i need is there a website that has a list of the equipment?
3.) anything else i need to know
Lots and lots of caves all over the world fit the category, knowing a general area where your from I would recommend a few. Standard equipment is similar to rock climbing so any mountaineering supply will have what you need. Top on the list is a quality light source and a couple of back up systems to that. Since your starting out go with folks who have been there and done that and follow directions closely. Several of the big caves have guided trips and that’s a great starter. Any way here’s a couple of links to get you started
