The Best Hotels in San Carlos

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.

Plunge pools come standard with every casita and villa at this rainforest resort inside Arenal Volcano National Park, which sets a certain tone early. Nayara Gardens sits at the kind of altitude where the canopy stretches out below your terrace and the volcano fills the rest of the view. Between ziplines, river rafting, and volcano treks, the outdoor shower barely gets used. Multiple restaurants cover the range from Costa Rican to Asian-inspired.
