Nayara Springs

Each of the 35 adults-only villas at this jungle resort sits over a spring-fed private plunge pool, with volcanic mud treatments at an open-air spa and Arenal's canopy right outside. Honeymooners fill most of the hammocks, but anyone who wants to disappear into a national park without giving up the oversized bathroom has found the right address. Michelin awarded it 3 Keys and Forbes a Four Star rating.
