There was a 5 minute boat ride and a one hour hike to reach Namtaloo (meaning "water goes through it") Cave. The hike was through lush rainforest and we had to cross a number of small creeks. When we arrived, some folks only came a couple hundred feet into the cave and then turned around. The rest of us (six) decided to hike all the way through the cave, which was about a half mile long.
There was a river running through the cave (hence the name) which we followed for a while, and then had to hike in for a while. We saw very large toads, the biggest spider I’ve ever seen, fish, crabs, and bats. Farther into the cave the passages got much more narrow and we had to swim in some areas that were over our heads (makes it hard to hold on to the flashlight). There were also a couple spots where we had to sort of rock climb down. There was one small waterfall in the cave that was quite cool to see.
After emerging from the cave, with our heartrates slightly elevated from our adventure, we hiked back to the boat and went back to Ton Toey rafthouses for more relaxation. The best part of being that far from any sort of civilization was the freedom to fully kick back. During the other parts of our trip, we did have quite a bit of free time, but I always felt like I should be out doing something or else I might be "missing" something. Relaxing at the rafthouses is the reason we are here, so there is nothing to "miss." Also, I wish I had brought a tape recorder to record the jungle noises at night – I have never heard anything like it.
