Nayara Springs

Just the simple facts about a place like this should be all the motivation you need: set in the Arenal Volcano National Park in central Costa Rica, Nayara Springs is a high-end adults-only hotel whose villas have everything from spring-fed plunge pools to indoor and outdoor showers and handsome traditional-style furnishings. 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.
