Jay Peak claims the most snow of any eastern mountain, famously hairy terrain, and a liberal off-piste policy. The only problem: there hasn’t been much else to do in this sleepy hamlet just shy of the Canadian border. A few years ago, the resort embarked on a $250 million revitalization program to provide what it’s calling a “weatherproof vacation.” Last month, Jay opened a $27 million water park under a retractable roof. There’s plenty to keep the kids busy: a pool, a hot tub, a standing surf wave, a sadistic water-slide called the AquaLoop—which sends riders into a 60-vertical-foot free fall—and a bar from which to watch it all. This month, the next phase opens with Hotel Jay, which offers 172 one-to-five-bedroom suites featuring spacious fireplaces and -locally made furniture (it’s Vermont, after all). The hotel’s best amenity? Free day care for powder-loving parents. Doubles, $179, including two lift tickets and water-park passes.
