Villas Rio Mar
Dominical Costa Rica 185-8000
This Polynesian-style sanctuary camps out next to the Baru River, within reach of four national parks. The spectacular Marino Ballena National Park contains the sands of several beaches and promises world-class snorkeling, coral reefs and rocky shorelines. Other nearby activities (which the hotel can help you organize) include surfing, humpback whale watching and rafting. There's an on-site spa where you can relax between adventures.
