Nayara Hotel and Spa (Arenal Volcano National Park, Costa Rica)

Is there a word for an oasis within a paradise? Nayara is a start, a collection of amenity-rich casitas, suites, and some 50 villas located in the lush rainforest jungle near an extinct volcano and lake. Unlike more rustic resorts that Costa Rica is famous for, Nayara offers thoroughly tricked out and modern accommodations that nonetheless are in harmony with the surroundings. The full-service spa is high on a cliff overlooking the jungle, and beyond the view offers treatments for couples or solo. Activities abound from whitewater rafting on the like to jungle and volcano excursions. Nayara's specialty is dining and wining, with a selection of on-site restaurants and a wine list boasting many of the best pours in Central and South america. [From $280/night for casitas up to $590 for villas; arenalnayara.com]
