Dalton Hot Springs flows at 109°F through the temperate rainforest of the Tongass National Forest on Prince of Wales Island. The spring maintains an elevation of 570 feet and delivers a 65-degree temperature differential above the maritime climate's 44°F average air temperature.
The thermal water emerges in coastal rainforest characterized by dense Sitka spruce and hemlock. The maritime setting brings consistent precipitation and moderate temperatures compared to Alaska's interior, creating a lush green landscape where the thermal spring stands out against cool forest streams and coastal weather patterns.
History of Dalton (Craig) Hot Springs
Dalton Hot Springs formed in mineral-rich bedrock beneath the Tongass, one of the nation's largest temperate rainforests. The spring's low mineral content (minimal calcium and magnesium, light sulfate at 20 mg/L) indicates relatively young thermal circulation in this geologically active region managed by the US Forest Service.
Access requires backcountry travel more than 10 miles from the Suemez Highway Road on Prince of Wales Island near Craig. Best visited June through September for stability. The Tongass National Forest manages these lands under open public access policy. Bring waterproof gear and expect wet conditions year-round with 87 inches of annual precipitation.
