Fodor's Expert Review Sonnenalp Spa

This lovely spa in Sonnenalp Resort is a European-style facility where you can relax on one of the lounge chairs around a crackling fireplace as you sip tea or spa water. Aspen trees stand over the heated outdoor tranquility pool, which has its own waterfall. Quench parched skin with a moisturizing HydraFacial, which diminishes wrinkles and shrinks pores (it's similar to microdermabrasion, but without the redness). You can also reduce altitude headaches with a hit from the oxygen bar. Book ahead for manicures and pedicures—they fill up year-round.
