The trails of Robertson Ranch are nestled between the neighboring communities of The Foothills and Robertson Ranch which border Agua Hedionda Creek. There are several trailheads you can take to access Robertson Ranch trails. The main parking for these trails is at Fire Station #3 on Trailblazer Way.

East trail: From Trailblazer Way you can access the Robertson Ranch trail east trailhead and can go north or south. When you head south, you’ll find a gently rolling trail leading over a seasonal creek which provides a great opportunity for bird watching and supports nesting habitat and protective cover from predators. As you cross the creek, you’ll notice a concrete berm architecture feature built into the landscape with culverts underneath. During a flood event water can run freely over the top without compromising the structure of the berm.

The vegetation in the open space of the creek area includes riparian scrub and marsh. Trees commonly found in this wetland community are willow and cottonwood and supports the overall ecological functions of the watershed.  This watershed eventually connects to the Agua Hedionda Lagoon to the south and west, which supports unique avian fauna, flora and aquatic species specific to California coastal lagoons.

Going north from the Trailblazer trailhead on Robertson Ranch Trail east will lead to the trail junction. If you continue east along Robertson Ranch HOA Trail this will take you towards College Avenue which leads through the hills and canyons of Calavera Hills open space with predominantly native coastal sage scrub flora. Take a rest in the shade of willows and cottonwoods as you hike through this beautiful valley. If you go west at the trail junction you will encounter a second creek crossing and the trail will ascend through preserved open space, revealing magnificent views of the Agua Hedionda Lagoon. The trail meanders between cul-de-sacs of the residential neighborhoods and connects to Edinburgh Drive trailhead.

West trail: On the western end of Robertson Ranch community, you can access Robertson Ranch Trail West at the Glasgow Drive trailhead. It leads southwest towards Robertson Drive. This trail is an isolated trail and does not connect to the two other trails inside Robertson Ranch.
