The 165-acre luxury Springs Resort & Spa nestles a thousand feet above the Arenal Valley just outside the national park boundary, higher than any other resort in the area and thus affording each one of its 47 polished-wood guest rooms commanding views of the Arenal Volcano and surrounding countryside and towns. Impressive as that view is, though, the resort’s biggest draw is its 28 mineral thermal pools that wind through four lush acres. The surroundings are undeniably romantic—the resort was featured in an episode of The Bachelor—but families are welcome, with activities for kids of all ages. Club Rio, on the resort’s kilometer of river frontage, offers tubing, river kayaking, mountain biking, horseback riding, and a wildlife preserve for rescued native animals, including monkeys, ocelots, jaguarundis, sloths, and a puma. Five restaurants (and five bars) mean there are plenty of options, from casual poolside dining to tasting-menu elegance.
