To sum up- this was one of the best excursions we have ever booked. We were two couples, and booked the private Crystal Dry Cave-Tubing experience, which was hosted by Adler. The pick up from the cruise port was smooth- we shared a van with one other group, and Adler Jr. gave a informative and entertaining running commentary about the country and it's resources and customs the entire way to the caves. We arrived at the caves, were given equipment, and the two groups broke off into their respective activities. Adler walked us through the jungle, teaching us about different plants, trees, and wildlife. We saw monkeys, and were encouraged to try the termites (we passed). Beautiful jungle walk, on mostly a flat, wide trail. Then we got in the tubes, directed and pulled/pushed by Adler. Again, informative and running commentary through the whole tour about the formations, water flow, and earth changes over time. The caves are GORGEOUS, and you will find nothing like this anywhere else, a totally unique experience. About half way through the tour, we stopped the tubes, got out and hiked through the caves. THIS IS NOT AN EASY WALK. You must be in good physical condition- up ladders, stairs, and over very uneven terrain, stepping over large crevices and ducking under rocks. However, if you are able, this is not to be missed. The glittering rocks, beautiful jungle peak-throughs, and the absolutely pure, crystal clear blue water is breathtaking. We saw some Mayan artifacts that were left in the caves, and Adler taught us of their uses and rituals done in the caves. Back to swimming through the softest, best feeling water I've ever seen, and to the tubes and cruising back out of the caves under Adler's power. Lunch was chicken and rice and beans in the van back to the port.
As I said, this was one of the best excursions we've ever done. We've traveled a lot and taken excursions in many places, and this one is well organized, beautiful, and unique. Communication from booking until pickup was excellent. Adler and Junior made the excursion relaxing and informative. Highly recommended.
*side note, you definitely want soled shoes that attach to your feet- you will be swimming in your shoes. Flip Flops will not work.
