Sapphire Lake (Trinity County, California)

Sapphire Lake is a small, glacially-carved lake located in the Trinity Alps Wilderness of Trinity County, California. The lake is situated at an elevation of approximately 7,500 feet (2,286 meters) and is known for its clear, deep blue water, from which its name is derived. The lake is fed primarily by snowmelt and rainfall.

Access to Sapphire Lake is typically via hiking trails, and it is a popular destination for backpackers and hikers seeking remote wilderness experiences. Common routes involve trails originating from trailheads along Highway 3 and are often multi-day trips due to the lake's location deep within the wilderness area. The terrain surrounding the lake is characterized by granite peaks, subalpine forests, and meadows.

Recreational activities at Sapphire Lake include camping (subject to wilderness regulations), fishing (requiring a valid California fishing license), and swimming. The lake is generally considered pristine due to its remote location and the relative lack of human impact.

Environmental concerns include the potential impacts of increasing recreational use, such as trail erosion and water quality degradation. Leave No Trace principles are strongly encouraged for all visitors to minimize their impact on the fragile ecosystem.
