This was my first time in a cave. Really neat experience, I'd recommend it. I took a guided tour with Cycle Solutions (a bit expensive for a solo traveler, but the price gets more reasonable if you have more people wanting to go) which included a mountain bike ride up a really fun, but challenging trail (for me, maybe easier or more difficult for others, depending on your trail riding experience) and then the tour through the cave itself. While I think anybody could get to the caves without a guide, I don't think I'd go through without someone who knows the caves. It's pitch black in most places and very, very tight in some spots. I wouldn't have believed we were going through such small spaces until we actually did it. Was really fun, I'd totally recommend it as an interesting experience!
