Sierpe del Pacifio is perhaps the most amazing experience with nature you'll ever have. The climb to the top is a bit grueling but the rewards are many. Although off the grid, there is still solar electricity and on demand hot water if you are conservative. The natural cabina is rustic but well designed and comfortable, with beautiful natural woods and hand-carved beams. The beds are very comfortable and the cabina is scrupulously clean. Just sitting on the back deck in the great leather rockers and watching the monkeys, toucans and other incredible species is worth the price of admission (bring binoculars and a decent cam era with a zoom lens).The welcome package you receive is amazingly well written and complete (and should be followed religiously). The excursions down the Sierpe river to Cano Island, Drake Bay and Corcovado Park are once in a lifetime experiences. DO NOT MISS the horseback ride with the charming Rosita. It may have been the best cultural experience of any vacation we have had. Guillermo will make sure your stay is completely hassle-free and is available by the provided cell phone.You really should just do this, it ranks in our top five "don't miss".
