The trail here is easy, flat, packed dirt along the neighborhood creek with ample shade. This is a great local trail and is relatively lightly trafficked. There is no parking at the western trailhead.

There is a picnic area here with sweeping views south toward the Pacific. There are a number of good popular local connecting trails to explore. The trails to the north lead up by neighborhoods, while the Bell View Trail south of here lends a greater feeling of being out in nature as it descends the ridge.
