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.
