Nayara Springs sits in the rainforest of Arenal Volcano National Park in Costa Rica, an adults-only retreat set among tropical forest with volcano views. Accommodation is in Springs Villas of around 1,500 square feet, each with a four-poster king, a private plunge pool fed by natural mineral hot springs, a garden with rain showers, a terrace daybed and a dedicated private host. Dining spans the fine-dining Amor Loco with a Costa Rican tasting menu, the Northern Italian Mis Amores with wood-fired pizza and volcano views, the private Besame Mucho, the Nostalgia wine bar, the Cielito Lindo swim-up bar and an espresso bar. There is an award-winning open-air rainforest spa using organic coffee, chocolate and volcanic mud, with yoga, plus a quiet pool and a main pool with a swim-up bar, and a sloth sanctuary on the Green Globe-certified grounds. Experiences are naturalist-guided, from zip-lining and waterfall rappelling to volcano hikes, birding and coffee and cacao tastings. A member of Relais & Chateaux, it suits adults-only couples and honeymooners who want a romantic, private rainforest escape with an award-winning spa and Arenal adventure.
