Nayara Springs

Both restaurants are quite frankly more impressive than they really need to be, as is the spa, whose open-air pavilions are surrounded by the treetop canopy. And the excursions are at least half of why you’re here: tour the canopy via elevated walkways, take a river safari or an ATV tour, or hike the volcano itself — there’s no end to the adventures on offer.

An adults-only enclave in the heart of the rainforest, this sustainability-minded Relais & Châteaux retreat has just 35 villa accommodations.

A treetop bridge leads from the main resort over enough lush tropical flumduggery to make a Kew Gardens employee weep. At the end is this, the newest, smartest addition to the Nayara brand. Villas are huge and eclectic: a Moroccan rug here; a Venetian mirror there; a floor of Mexican hand-painted tiles.

Perched at the top of a rainforest, surrounded by tropical plants and creeks with gorgeous views of the Arenal volcano... this adults-only hotel gets high scores for service, and the spa has indulgent treatments with volcanic mud and chocolate clay.

The adults-only Nayara Springs is one of the most intimate and luxurious hotels in the country. It has exuberant tropical gardens full of exotic birds and fish, giving a sense of Costa Rica coming to you.
