Akutan Hot Springs, Natural hot springs in Akutan Island, Alaska, United States
Akutan Hot Springs is a geothermal system with dozens of thermal pools and at least one geyser, distributed across five separate areas in Hot Springs Bay Valley. The heated water feeds several streams and creates a landscape of natural hot pools shaped by surrounding rock formations.
The system originates from volcanic activity linked to Akutan Peak, a stratovolcano that has shaped the island's geology. The thermal waters have remained continuously active, powered by the island's ongoing geothermal processes.
The springs are a natural feature of the Aleutians that local communities have long valued and used. The hot waters shape the landscape and remain part of how people experience this island environment today.
Access requires a boat or aircraft, as the springs sit on a remote Aleutian island with no road connections. Water temperatures can reach 77 degrees Celsius (171 degrees Fahrenheit) in pools and streams, so careful approach is necessary when entering these areas.
The waters emerge directly through beach sand and rock fissures, creating natural basins in the surrounding sediment. This direct coastal setting distinguishes these springs from many other geothermal systems in the region.
