We came here during the dry season (March) and had to drive on dirt roads (not bad ones) and through two small rivers (you'll want an all whee drivel SUV) to get to Mike's Place. We didn't have a guide booked in advance so we had to wait around for a half hour or so. There's a little walk to wander and a restaurant. Our guide was great! He had lots of information to share, kept it PG for the kids and answered all our questions. We canoed about 1 km into the cave and saw some nice formations and Mayan artifacts (not too many). Lights were provided although we did have our own headlamps too. There were maybe two other groups we passed, which was nice and kept the experience quiet. Our guide said it is busier on a weekend. And he said if you want to see bigger bats - not just insect bats - try to be on one of the first two tours. You can swim in the water outside the cave after (there are little fish in there and both shallow and deep areas), so bring a towel and swimsuit. Swimming could be a good idea to do after you've ordered food as it takes a while. We had fresh coconuts chopped off a tree just for us!
