The dramatic terrain around Pacifica makes for some wonderful areas to enjoy mountain biking. Unfortunately, there are no lengthy off-road loops. However, those with a bit of imagination can create some challenging loops should they concede to ride on a little pavement. Areas where mountain biking is allowed are multi-use trails, so be prepared to share. You will find that most people in the area are rather friendly towards cyclists that exhibit some sort of common sense and courtesy.
Many trails are loaded with blind turns and low shrubbery, so please use caution.
The Mori Ridge Trail is the best way to get to Sweeney Ridge from Pacifica. The Shelldance Nursery is located just past Reina Del Mar on northbound Highway One. Just after cresting the mountain, riders will connect with the fire road that brings you to the peak of Montara Mountain. To reach the trailhead from Highway One, cyclists must turn onto Linda Mar Blvd. and travel east until you reach Adobe Drive. The trailhead is at the end of Higgins, but the area around that intersection is better suited for parking, should you need it.
