We did the cave tubing at Jaguar Paw in June, 2003, and it was one of the most unique travel experiences I have ever had! You will love it. We wore old tennis shoes because we had heard we would need them for the jungle walk, but we did NOT and wish we had had Teva's or watersocks. You might check and make sure that you are not going on a day when a cruise ship is in port as I have heard the caves are VERY crowded on those days. Be sure to eat a termite from one of the trees on the jungle walk! Yes, I am serious! Our guide did, so I tried one too! Enjoy.
