The summit (2572ft) of Mt Tamalpais is accessed via a short, but steep hiking trail leading 0.3 miles uphill to a fire lookout with awesome ocean-to-bay views. From Pantoll Station, it’s just over 4 miles by car to the trailhead; turn off Panoramic Hwy on to Pantoll Rd, continuing on panoramic Ridgecrest Blvd to the summit parking lot.
