A beloved though demanding hike, the 7-mile Dipsea Trail climbs over the coastal range and down to Stinson Beach, cutting through a corner of Muir Woods. This classic trail starts at Old Mill Park with a climb up 676 steps in three separate flights, and includes a few more ups and downs before reaching the ocean.

The few slaloms between staircases aren't well-signed, but locals can point the way. West Marin Stagecoach route-61 buses run from Stinson Beach back to Mill Valley at least a few times every day, making it a doable one-way day hike. You can refill water bottles and grab a snack at Muir Woods Trading Company cafe, about a 2-mile hike from Mill Valley, or start or end the trail there instead.
