About Upper Warm Spring

Upper Warm Spring is a naturally heated pool tucked away in California’s rugged Inyo County. This primitive warm spring offers an unrefined soaking experience surrounded by quiet desert landscapes, inviting you to connect directly with nature’s raw warmth and tranquility.

Getting There

Reaching Upper Warm Spring involves a moderate hike through rough terrain, so prepare for an off-the-beaten-path adventure. There is no designated parking lot, but you can leave your vehicle at a nearby trailhead before navigating the dirt paths by foot.

What to Expect

The water here remains comfortably warm, flowing into a simple, naturally formed basin without any built structures. The atmosphere is peaceful and isolated, with very few visitors compared to other hot springs in California. Facilities are non-existent, so all essentials come with you.

Tips for Visitors

Visit during weekdays or shoulder seasons to avoid any chance of company at this primitive spot. Bring plenty of water, snacks, and sturdy footwear since there are no amenities or developed trails. Respect the delicate environment by packing out all trash and leaving the area unchanged. No fees apply.
