At the crest of Panoramic Highway and the end of A Panoramic View, the summit of Mount Tamalpias still lies four miles away. Before reaching the top of Mt. Tam, you will have to conquer Pan Toll Road.
To begin the next stage of ascending Mt. Tam, turn right from Panoramic Highway onto Pan Toll Road.
Pan Toll Road is the entrance to Mount Tamalpais State Park.
The first section of climbing is step with very little shoulder room, so watch out for the passing by.
You will get a slight reprieve from the constant climbing and the road will level off for a short stint before the steep grade returns. The road turns around corners as the grade changes from gradual to steep to moderate. Theses series of turns will take you to the one mile marker of the route where you are presented with your first opportunity to break.
The first rest area is a great place to take pictures of your adventure and to rehydrate.
The last part of the climb is short, but extremely steep all the way to Ridgecrest Boulevard.
There is one more rest area along the last section of the climb. This is a good place to stop if you need a short break. At the end of the climb along Pan Toll Road you will reach Rock Spring.
Rock Spring is at an elevation of 1940 feet above sea level. The slight descent along Panoramic Highway increases the total elevation gain from Marin Crossroad to over 2000 feet! Once you reach this point, you can either turn left onto West Ridgecrest Boulevard and take in the spectacular views of Stinson Beach and Bolinas below, or turn right onto East Ridgecrest Boulevard and begin the final stage of ascending Mount Tamalpais.
Reaching the top of Pan Toll road is no small feet, with over 2000 feet of climbing, conquering this advanced route is what many Bay Area bikers do when they are up for a challenge and want a spectacular descent as their reward. The steep climbing turns into steep descending with technical twists and turns as you make your way back to Mill Valley or Sausalito.
