Over a thousand acres protect a beautiful river, waterfalls, rainforest varieties of plants and animals and a beach. This is a really rewarding getaway from the stresses of the world, especially since it's so close to Corcovado, the Rio Sierpe Mangrove Swamp and Forest, Rio Claro and Isla del Cano Reserve. The lodge offers tours through the reserve, as well as to Rio Claro, Corcovado and Isla del Cano that include a naturalist guide and lunch. You can even rent snorkeling equipment for the island tour. In fact, many boats leave from Marenco and sail by this small island that was set aside to preserve surrounding sealife, oceanic birds and plants living on the island.

At any rate, you can still see these spheres today, as well as sunbathe, go snorkeling and swimming on its sandy shores.
