Is it possible to float down the Caves Branch River without going through a tour operator? I have read many TripAdvisor questions and comments, and done several web searches, and all searches lead to Caves Branch Jungle Lodge and Tours. We will be driving from Placencia and San Ignacio and would simply like to stop off the highway and float down the river! I realize that's over simplifying it, but the point is really that we don't need to go through all the effort of scheduling a tour bus, etc. etc., We just need to rent some tubes and find an entrance point. Thanks for the advice!
