About Mineral Spring

Mineral Spring in Alaska offers a raw and authentic encounter with nature. This warm spring heats the water to a steamy 136°F, creating a soothing oasis amid the rugged wilderness of Copper River County. Its remote location and intense heat give a powerful sense of solitude and rejuvenation.

Getting There

Reaching Mineral Spring requires effort and planning. Access demands either a boat or floatplane ride followed by a strenuous hike lasting over an hour. Limited parking near the trailhead means you should arrive prepared for a bit of a trek through untouched Alaskan terrain.

What to Expect

The spring’s waters stay hot year-round, enveloping you in comforting warmth even against Alaska’s chill. The primitive setting means there are no built facilities, lending to an undisturbed, peaceful atmosphere. Crowds are rare here, often leaving the spring to you alone.

Tips for Visitors

Dress in lightweight, quick-dry clothing to handle the intense heat and changing outdoor conditions. Visit during any season, but be ready for unpredictable weather and trail challenges. There is no clear fee structure, so carry some cash and respect the natural environment with Leave No Trace principles.
