The Trinity Mountains are a subrange of the Klamath Mountains, one of the ranges within the California Coast Ranges and part the greater Pacific Coast Ranges, the coastal mountain system extending from Mexico to Alaska. The Trinity Mountains subrange rises in Siskiyou County and eastern Trinity County, Northern California.

They are protected within the Shasta-Trinity National Forest.


The Trinity Mountains run in a southwest-northeasterly direction for 30–35 miles (48–56 km). The subrange runs between Trinity Lake and Lake Shasta, around 17 miles (27 km) northwest of Redding.

Peaks of the Trinity Mountains rise to elevations of 4,000 feet (1,200 m) in the southwest, and to more than 7,200 feet (2,200 m) in the northeast. Mount Eddy is the highest peak, at 9,037 ft (2,754 m), which is highest point of the northern segment of Pacific Coast Ranges within the lower forty-eight states.
