Caving $ 🎓 💪💪

I've done a lot of caving, but mostly on tours.   They have climbing tours where you climb, floating tours where you float down an underground river, as well as the far more common walking tours.

Almost all caving tours are cheap - minimal equipment and training required.  Do NOT just go into a cave without a lot of training and safety equipment.  That way lies death.  Getting lost or hurt is easy without a guide, and human presence can dramatically affect the cave - your hand print leaves oil that will affect the wildlife that lives there.  Going on a tour doesn't take much skill, but without a guide, you need a lot of knowledge.  Basically, going without a guide is for experts, and if you are getting any information about caving from me, you are not an expert.

Everyone likes to check out caves - young and old, men and women.  You obviously need a flashlight.  If you are in a river cave, you will need a life jacket and possibly a wet suit.  You definitely want water shoes of some kind.  Tours should provide this.

Walking and floating tours require you to be in reasonable good shape, but not more than that.  Climbing tours are for the more advanced people.  They take more skill and muscle.

Of the tours I have taken, I liked the floating tour the best.   It was in Mexico, near Cozumel, at the Rio Secreto:
