Marin County Parks Open Space Preserve

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.

• East access: from Highway 101 in San Rafael, take the exit for Central San Rafael west. Follow 3rd St approximately 1 mile, continue on 2nd Street, which merges into 4th Street. 4th Street turns into Red Hill Ave after 0.6 mile; follow for 0.5 miles. Stay right onto Sir Francis Drake Boulevard and follow 3 miles, turn right onto Glen Drive and follow 0.5 miles to end (dead end).

• West access: from Highway 101 in Larkspur, take the exit for Sir Francis Drake Boulevard west 6 miles. Park in the big gravel pullout on the right side, below the crest of White Hill.

Help us keep this trail beautiful and dog-friendly:

• Respect and protect wildlife and habitats
• Pack in and pack out, leaving only paw prints

Wide Open Spaces
The Marin County Open Space District, which turns 40 this year, was born from a heroic movement to preserve natural lands and contain urban sprawl. Today it administers 34 preserves—all but one of them dog-friendly—totaling more than 20,000 acres and providing Bay Area residents and visitors with many ways to play. Four-legged hikers enjoy the rare privilege of accompanying their humans off-leash on the fire roads in the preserves, and while tethers are required on other trails, none of the paths are off limits to canines.  more »

Boy and dog in Bon Tempe MeadowMore than 60,000 dogs live in Marin, according to estimates from the Marin Humane Society. Open space is the draw for residents and visitors alike, with tens of thousands of acres available for on- and off-leash activities. The Marin County Open Space District alone manages 34 preserves totaling 15,000 acres open to public recreation. At all but 10, well-behaved dogs under voice control can accompany you unleashed on fire prevention roads. more »
