Rios Tropicales offers a 2 day river rafting trip that is like nothing else in Costa Rica. It is great for a couple reasons.
#1 you are slitting up your drive time between 2 days, which makes it much more bearable.
#2 The way they have it set up is just awesome. You drive out to the location (they pick you up in San Jose) you start your rafting trip on the Pacuare River. I believe the first day there is 4 hours of rafting. You arrive at the river front lodge, deep in the rainforest, via your river raft where your bags are waiting for you. Nice.
#3 They have a short Canopy Tour included in the package there at the lodge.
#4 the next day you head back out on the river for the second leg of your adventure. When you finish up your bags are waiting in the vehicle and they drive you directly back to San Jose. It is one of the best run tours I have encountered anywhere in the world.
These guys do a wonderful job, for many visitors, it is the highlight of their entire trip to Costa Rica. Although I must say, those that rave about it have not had a threesome with Laura and Pamula.
