Our trip was great. Dave and his crew are wonderful. The drive to the caves is a little over an hour and they gave us all kinds of info about the country and the people. They told us about the local wildlife we might see. It was a really fun ride. The groups are small so the service is very presonalized. They answered any questions we had.
Once we got to the cave site we all grabbed our tubes and set off on our walk to the cave. It is about a mile thru the jungle with some pretty steep terrain. It was also raining so it was pretty muddy. Don't wear flip flops. Several of the young girls had them on and they kept getting stuck in the mud. Once you get to the river they hook all the tubes together and we set off. Dave and his guys walk the river where they can and ride tubes wher the river is too deep. They point out all the formations and take you to a little waterfall in the cave that other groups seem to pass up. Once out of the cave it is a really nice float down the river back to the starting point so you only carry the tubes a short distance back. We noticed other groups getting out of the river much sooner. Dave told us they were the groups who booked with the ships and they don't drift down the river.
So again I would highly recommend Dave and his guys if your going to go cave tubing, go with cavetubing-r-us. They are the best
