Don't leave CR without seeing the red eye green frog which is the symbol of CR. We saw so many of them in the night trek that I stopped taking pictures after spotting the 10th one. We were so close and I really zoomed in with the camera for excellent shots. We saw at least another 6 types of frogs, including the long-nose, bull, gladiator, common tree, and others that I forget the name. We even spotted several sleeping sloths, and a very active kinkajoo. Plus lizards, JC baselisk, a snake, and their captive turtles and crocs. The tour is only two hours long, but it flew by so quickly because it was constant action. Even I spotted a few frogs. Tour guide Henry is very knowledgeable and efficient, and he really respects the environment.
