Amor Arenal

Thirty-one casitas spread across a hundred-odd acres of rainforest, each with its own plunge pool and an unobstructed view of Arenal Volcano straight through the trees. This is a luxury rainforest resort that sits where most hotels don't bother, right at the park's edge, well away from the coasts. Local materials, low-key in atmosphere but not in comfort, and enough guided expeditions, from volcano hikes to sloth-spotting, to justify staying a week.
