I just got back from a week in Belize, and our group of 6 went cave tubing. There was a long hike through the jungle, and one of our group is almost 7 months pregnant. The hike wasn't exactly strenuous, but the narrow mud path was very slippery and there were lots of opportunities to slip in the mud, trip over a branch, fall into a hole or off the trail, etc. One needs to wear good hiking boots or those scuba shoes with good traction. I wore Teva's, and most others wore sandals, which survived, but were not the best footwear. Load up on bugspray, a good meal and lots of water before starting the hike. Anything you carry/wear will get wet, and there are no garbage cans in the jungle. The hike was about 90 minutes, the tubing down the river about 40, the ride back to the nearest restaurant (Cheers) about 30. Then there's the hour ride back to Belize City, and in our case, the 15 minute flight back to AC. We all wore shorts and t-shirts over bathing suits, and there was minimum humidity - quite surprising. That said, the experience was fantastic. Our guide was a full Mayan and had grown up in the area. He explained all the plants, animals, and insects in the jungle, and gave us fresh wild rhubarb. Great for thirst and hunger. The caves were awesome, the scenery amazing, and I'd do it again!
