Casa Roja is a wild, unforgettable experience in the heart of nature. Located at the northern tip of the undeveloped Osa Peninsula, the house sits atop a perch overlooking where the Sierpe River meets the Pacific Ocean. This offers spectacular panoramic views of the river mouth, locally known as “La Boca.” Casa Roja is like an island at the edge of the water and forest, situated in a roadless area only accessible by boat. To the north lie the Terraba-Sierpe National Wetland, the largest intact mangrove forest in Costa Rica. To the south are many protected areas, including the Golfo Dulce Forest Reserve, Piedras Blancas National Park, Rio Oro National Refuge, and Corcovado National Park, the crown jewel of the Osa Peninsula. We provide transportation to and from Sierpe or Drake Bay, and we can arrange tours for all excursions and activities departing from our remote locale. There is no other property like this in Coast Rica, and perhaps the only house where you can watch the sun rise over the river and set over the ocean!

Our team at Casa Roja has a deep love for Costa Rica, as well as a long history of environmental research, education, and conservation. We see the lodge as a unique opportunity to introduce guests to the spectacular natural beauty of the Osa Peninsula, as well as the Sierpe River and its special mangrove forests. At the same time, we strive to support research, education, and conservation in the region by working with communities, universities, and environmental groups. We hope that more people sharing our love and appreciation for this incredible region will help support its preservation for generations to come.
