We hiked into Corcovado National Park on our fourth day on the Costa Rican Osa Peninsula. The hike took us into the rain forest but the path was parallel to the ocean. Although we couldn’t always see the water, we could hear the sounds of waves breaking on the shore mingled with monkey screeches and toucan calls. Every mile or two, the path took us back to the ocean and we walked across the dark sandy beach until we reached the next trailhead into the rainforest. The mists clung to the hillsides making the vista quite mysterious. These hikers were heading back toward the park entrance.
