The hook
The mountain the whole Bay Area looks up at, with a fern-and-redwood canyon of wooden ladders on one side and the open ocean on the other.
01Why it's worth it
Mount Tam is Marin's presiding peak, and the reason to climb it isn't the drive-up summit, it's the trails getting there. The Steep Ravine trail drops through a dark, fern-draped redwood canyon along a creek, complete with a wooden ladder you climb down beside a small waterfall. The Matt Davis trail runs the open slopes with the whole Pacific laid out below, all the way down to Stinson Beach. String them into a loop and you get redwood canyon, coastal meadow, and ocean in a single day, forty-five minutes from the city. And if you can't do the big hike, the paved Verna Dunshee loop at East Peak hands the summit panorama to everyone.
02How to experience it
The classic is the Matt Davis to Steep Ravine loop from Pantoll down to Stinson and back, a hard full day. If you only want the view, drive to East Peak and walk the flat Verna Dunshee loop. Check trail status first: a stretch of Steep Ravine has had closures, with a detour around it via the Dipsea trail.
The honest note
The big loop is a real hike, not a stroll — roughly 7.5 miles and 1,700 feet, as a Bay Area hiker specifies: "park at Stinson, head up the Matt Davis Trail to Pantoll, then come back down Steep Ravine… It's about 7.5 miles / 1700' of elevation." Do it in that direction; climbing the open Matt Davis slope in afternoon sun is the version people regret.
Parking at Stinson Beach fills early on any clear weekend, and the Panoramic Highway shoulder is enforced.
Fog decides the day, not the forecast. The coastal side is often socked in when the city is clear, and the summit view that justifies the drive-up simply is not there. Steep Ravine is the fog-proof half — the redwood canyon is better damp.
The ladder in Steep Ravine is genuinely a ladder, wet and slick after rain. Fine for most people, not for dogs or small children.
From the locals
The most-upvoted description of what this mountain is for is not about the view at all: "Muir Woods! Drive over and park in Stinson beach. Take the steep ravine trail up and go around the dipsea loop. This is my absolute go to when I need to clear my head and it never disappoints. We live in an incredible area!"
The route specifics, offered to someone asking for demanding, beautiful hikes near the city: "Marin has oodles of hikes like that. A particularly good one (imho) is to park at Stinson, head up the Matt Davis Trail to Pantoll, then come back down Steep Ravine."
And it is the first thing named when someone moving to San Francisco asks what they have got themselves into: "Do you like nature? You're moving to an area with some of the most beautiful hikes in America. Less than an hour north or south, you have Tamalpais, Pacifica, half moon bay, Point Reyes."
