Trail shared by Phil DiGirolamo

Up and down or down and up, either direction you'll be mesmerized. The coastal view is stunning.

Runner Notes

There is variety in this singletrack, you will be in and out of shaded areas, rollers to go up and down as well as a nice descent or climb depending on your direction.


From way atop the hill where Highway One and the Panoramic Highway intersect, there is a parking lot just past the big sharp turn. Hop on that trail going west and you'll start your descent to the coast and Muir Beach, right across from the Pelican Inn. Dont mistakenly take the trail to the right that descends into Muir Woods, unless that is your intended destination.

As one would expect when facing west, the views will be absolutely stunning. See if you can detect the Farallon Islands, and the tankers and cargo ships. Look northward and you'll see Duxbury Reef and even Point Reyes. This is all downhill with the steepest portion being near the bottom before the Pelican Inn. Save some energy for the return trip if you go east to west!

Flora & Fauna

This is one of the largest of the chaparral areas left in Marin County. Trees are overgrowing other areas because of the lack of wildfires. The canyon to the north leads to Muir Woods, so naturally there will be redwoods, oaks, laurel and more. Pines line the ridge and there are plenty of soaring birds that you can almost touch.

This part of the Dias Ridge Trail leads to the peak, just before you start your descent.  Look for the line of dead pines and you'll be past the half way point.  All downhill from here on the west direction.
