Total Elevation: 2,125 feet
Distance: 13.1 miles
Approximate Time: 1 hour 10 minutes




The Muir Loop is a must-do, local Marin County ride that we refer to as the ‘lunch ride’. At approximately 60 minutes in duration with about two thousand feet of climbing with no steep pitches, this ride can be done in either direction once you arrive to Four Corners. From downtown Mill Valley, the counter-clockwise direction is shown above. We do not recommend climbing from Tam Junction up Highway 1. This ride passes through the historic Muir Woods National Monument and the Golden Gate National Recreation Area.

The rider needs to navigate a few turns in town but it provides the most scenic, car-free route up to Four Corners. The ride begins at Studio Velo by turning right to head northwest on Miller Ave, jog around the town plaza by going left at the stop sign and then right. Turn left on Throckmorton Ave, followed by another left onto Cascade Dr, bearing right up the Canyon. Take a left on Marion Ave and wind your way up to Edgewood Ave where you continue to climb up to Four Corners.

At the top, take a breather on the East Side of the road and enjoy the view of the ocean and the expansive San Francisco Bay. Drop down Muir Woods Road until you hit the entrance of the famous Muir Woods Park. Continue along the flats until you reach Highway 1, where you will turn left and begin your accent up to the famous Highway 1 climb back towards Tam Junction. At the top just continue over the hill down a relatively technical descent (being cautious of the deep pavement grooves in some of the corners), returning to Studio Velo.
