Goddard Hot Springs flows at 153 degrees Fahrenheit from just 60 feet elevation on Baranof Island south of Sitka, maintaining a remarkable 109-degree temperature differential in the temperate rainforest environment.
The springs emerge within lush Sitka spruce forests receiving 101 inches of annual rainfall, creating misty thermal pools surrounded by moss-covered rocks and rushing streams in one of Southeast Alaska's wettest ecosystems.
History of Goddard Hot Springs
Named for Captain George Goddard, the springs reflect deep circulation through Mesozoic metamorphic rocks along the Alexander Terrane, with thermal anomalies suggesting active hydrothermal convection in fault-controlled systems.
Reservable cabins at Kanga Bay (5 kilometers away) provide a weather-permitting base for visits via floatplane or boat from Sitka. Plan for intense maritime weather and bring waterproof gear year-round.
