his full day tour, accompanied by a naturalist guide, begins right after breakfast. A short 25-minute boat trip from mainland landing takes you to San Pedrillo Station, the northernmost ranger station of Corcovado National Park. After disembarking, there is a walk of about an hour along the beach, to a forest trail up the Rio Pargo. Once more the rain forest story unfolds before you. The trees in this area are magnificent in height and support an outstanding variety of epiphytic plants such as orchids, bromeliads, ferns-even shrubs and small trees. Monkeys, agoutis, sloth and other critters will entertain you. By noon, the tour returns to the beach to enjoy the shade of a mango tree while watching the surf. After lunch time, a short walk; the San Pedrillo river (time to get our feet wet) brings you to a pristine rain forest waterfall. As always keep your eyes peeled for beautiful birds and secretive wildlife. Kingfishers and Jesus Christ lizards are residents of this river. In late afternoon, we board the boat for return to the hotel..
