Indian Indulgence

For a historic soak with contemporary comforts, consider Calistoga's Indian Springs in northern Napa Valley. Surrounded by palm trees, and with a retro-chic vibe, this steaming, spring-fed oasis was first used by the Wappo Indians; now its Olympic-sized pool entices visitors from around the world. Access to the pool is limited to those overnighting at Indian Springs or getting a treatment at the spa; the least expensive treatment is the 25-minute massage for $65, which will leave your muscles loose and your limbs noodly. (If you want to splurge, mud baths are their signature indulgence.) Mix up your soul-warming soak with a nap or a snack near the outdoor fireplace. There's also a Buddha pond respite, good for splaying out and just chilling. Overnight guests have full access to the hot springs until midnight. Sweet steams.

BONUS: Also worth a stop is nearby Vincent Arroyo Winery, where bargain prices (for Napa) meet supreme taste.

Indian Springs, 1712 Lincoln Ave., Calistoga; 707-942-9035 ext. 11. Spa visitors have access to the pool until 5:00 p.m. Overnight guests can stay in one of 24 lodge rooms or 16 cottages. Prices start at $250 per night on weekends.
