Loma Alta Preserve
Fairfax, CA 94930
Natural Area: Birding, Picnic, Walk
Rising to a height of 1592 feet, this “tall hill” is actually one of the highest points in Marin. The ridge lines that run together to form Loma Alta divide the four major watersheds of the county: Miller Creek to the northeast, Corte Madera Creek to the southeast, Lagunitas Creek to the southwest, and Nicasio Creek to the northwest. This 509 acre preserve encompasses most of the grass-covered south facing slopes of this broad, gently sloping hill. Running along the lower perimeter of the preserve is the Old Railroad Grade Fire Road. During winter, a prominent feature of this lower trail is the 25-foot cascade known as Fairfax Falls. To reach the summit, take the Smith Ridge Fire Road, or the extremely steep Gunshot Fire Road. Either way, spectacular views of the entire Bay Area will reward you each time you stop to catch your breath.
