Lapa Rios, Osa Peninsula
Former Peace Corps workers, John and Karen Lewis, moved from Minnesota to Costa Rica in the Nineties to develop a tract of rainforest into a conservation project and private reserve. The result was Lapa Rios, which pokes out of the canopy with 16 thatched bungalows, close to Corcovado National Park. Each lodge is open to the elements on three sides, with only a mosquito net separating the beds from the balconies. A communal pool and restaurant invite guests to trade tales of adventure.
