About these waters
Off Benton Crossing Road on BLM land in the Long Valley Caldera, Wild Willy's is a free, clothing-optional soak reached by a quarter-mile boardwalk from the parking lot. Two tiered pools fed by geothermal water sit beneath open sky with sweeping views toward the Sierra. It's accessible around the clock with no fees or reservations; basic pit toilets are the only facility, and winter access can require a snowshoe or ski approach.

Good to know
- Listing researched October 2026 — prices and hours change, always confirm with the spring before visiting.
- Hydrate between soaks and limit hot soaks to 15–20 minutes — mineral water dehydrates fast.
- Wild springs run on the honor system: pack out everything, leave the pool cleaner than you found it.

Wild Willy's Hot Springs: FAQs
Do I need a reservation or permit to visit Wild Willy's Hot Springs?
No reservations — wild springs are first-come, first-served. Some trailheads require a parking pass or day-use fee, so check the listing details and current land-manager rules before you go.
What should I bring to Wild Willy's Hot Springs?
Swimwear and a towel, drinking water, a trash bag (pack out everything, including food scraps), and a headlamp if you're staying for sunset. Never bring glass near a wild spring — broken glass in a pool ruins it for everyone.
Is the water temperature reliable at Wild Willy's Hot Springs?
Wild spring temperatures shift with seasons, rainfall, and river levels — a pool that's perfect in October can be scalding or flooded in May. Test the water with a hand before getting in, and check recent trip reports for current conditions.
