About Hot Spring On Umnak Island

Hot Spring On Umnak Island offers a striking encounter with Alaska’s rugged volcanic landscape. The spring’s steaming waters, heated to around 149°F, create a raw and elemental bathing experience amid the wild terrain of the Aleutian Islands. Its combination of intense heat and remote setting invites you to connect deeply with nature’s geothermal power.

Getting There

Reaching Hot Spring On Umnak Island requires a hearty spirit and careful preparation. Access involves travel by boat or small plane to the island, followed by a challenging hike across uneven volcanic ground. There is no developed parking or trails, so sturdy footwear and wilderness navigation skills are essential.

What to Expect

The hot spring pools are primitive and uncultivated, with scalding water that demands caution and respect. The atmosphere is completely natural and solitary—crowds are virtually nonexistent due to the site’s remoteness. There are no facilities, only untamed beauty and the intense heat of the spring blending with Alaska’s stark landscape.

Tips for Visitors

Plan your visit with safety in mind: approach the spring slowly to acclimate to the high temperature, and bring sufficient water for hydration. The site has no fees but no amenities either, so carry all necessities. Best visited in summer when daylight is long, navigation is safer, and weather conditions improve.
