Description

The Horse Hill section of the Alto Bowl Open Space has a network of fire roads and trails from Camino Alto Road in the north to Lomita Drive in the south. This horse pasture offers a spot in the midst of the city where you can get some fresh air. Walk through woods and grassland as the pathway snakes between residential neighborhoods. The area can get muddy in winter and spring. Plan to wear good hiking shoes if you come during the wet season.

One trail access point to this route is at the open space gate located at the end of Coach Road. Here, you'll start on the Bob Middagh Trail. Head through mixed woods for a short distance before entering the grassy area. Walk along the dirt lane as you pass eucalyptus groves and a cluster of Calfornia bay and oak trees. You'll descend into a section with willow trees and blackberry bushes. 

The trail climbs then back to meet the Alto Bowl Fire Road in a clearing. Follow the road past the gate to the cul de sac and look for a small wooden fence that marks Horse Hill Trail. At first, this footpath has a steep incline. You'll pass some coast live oak and a few homes before re-entering meadows. From the top of the hill, there's a puptacular view of Mount Tam. You might even catch sight of the San Francisco skyline if it's clear. From the crest, there's a fire road that descends to Lomita Drive. 

When you're hiking with your furry pal in this preserve, they can be off-leash on the fire roads. On other trails, remember to keep them on a lead. Bring water and bags to remove waste with you.

The trail system that wanders through Horse Hill in the Alto Bowl Open Space Preserve offers a place in the city where you and your pooch can get exercise. Hike through some woods and pasture and climb the hill to catch pawmazing views of the area.
