My extended family just returned from a week in Costa Rica--our first trip to Manuel Antonio. How lucky to find Aguas Azules and Melanie and Miguel. Like Rhonda E., they were recommended by our hotel and I couldn't be happier. My older son wanted to try parasailing, and convinced my younger to join him. Both teenagers were anxious to appear confident, but were a tad fearful underneath. Melanie was so great with them: knowledgeable, efficient, friendly and calm. She put them at ease without letting on at all that they might have some butterflies in their stomachs. Before I knew it, they were rising gracefully into the air. What a wonderful experience!! We plan to return someday for the fishing and snorkeling tours (which A.A. also provide). Professional and friendly.
