Overview
Mount Tamalpais State Park sits above Mill Valley with 60-plus miles of trail and, at East Peak, one of the most accessible summit views in Northern California — ocean, Bay, San Francisco skyline, and on clear days over 50 miles to Mount St. Helena. The easiest family entry point is the paved Verna Dunshee Trail at East Peak: a 0.7-mile loop around the summit that is flat, fully paved, and accessible with a jogging stroller. For families who want actual trail time, the Bootjack and Pantoll area trailheads open up loops through old-growth redwood and chaparral that work for kids 4 and up who hike regularly.
How to Do It
Take Highway 101 to the Highway 1 / Stinson Beach exit in Mill Valley, then follow Highway 1 west. Bear right onto Panoramic Highway toward Muir Woods and Mount Tamalpais. Follow Panoramic Highway north past the Mountain Home Inn area, turn right onto Pantoll Road, then right again on East Ridgecrest Boulevard at the Rock Spring lot. East Ridgecrest takes you to the East Peak parking lot at the summit.
Parking at East Peak costs $8 per car ($7 for seniors) — pay via cash, check at the self-registration box, or through the Yodel app. The same parking permit covers Bootjack and Pantoll lots that day. East Peak lot is smaller than it looks and fills by 11 a.m. on clear weekend days. Arrive by 9:30 a.m. or use the Rock Spring lot on East Ridgecrest as an overflow option, which has more parking and is a short walk or additional hike away.
For the simplest family experience: park at East Peak, walk the Verna Dunshee Trail loop (0.7 miles, flat, paved, 30 minutes), visit the Gravity Car Barn and the weekend-only Visitor Center at the summit, then head back. For families who want more: drive down to Bootjack or Pantoll and pick up the Easy Grade Trail, which follows gentle switchbacks through chaparral to Mountain Theatre. The Fern Creek, Lost, and Canopy Trail Loop out of the Mountain Home Inn area is 3 miles with 593 feet of elevation gain — manageable for fit kids 5 and up who hike regularly, and one of the most-reviewed kid trails on AllTrails with a 4.8 rating.
Tips & Tricks
Fog is the main variable on Mount Tam. The summit at East Peak is frequently fogged in through mid-morning, particularly in summer. The fog usually burns off by noon on clear-forecast days, but it is entirely possible to drive up and see nothing but white. Check the forecast for Mill Valley the morning you go — if the coast shows fog at 10 a.m., wait until noon to head up, or go in April or May when fog patterns are lighter.
The Visitor Center at East Peak is only open on weekends, typically 11 a.m. to 4 p.m. (Gravity Car Barn 12 to 4 p.m.). A seasonal snack stand operates intermittently during summer — treat it as a bonus rather than a meal plan. Bring all your own food and water; there's nothing guaranteed to be open at the summit.
The Pantoll parking area is the hub for the park's more popular trail systems but has limited spots. Rock Spring at the intersection of Ridgecrest and East Ridgecrest has more parking and is the better base for families doing longer loops toward Cataract Falls. Cataract Falls is most impressive in winter and spring after rains — by August it's a trickle. If waterfall payoff is the goal, go in February through April.
Layers are non-negotiable. The summit runs 10 to 20 degrees cooler than Mill Valley and the ridgeline wind can be sharp even in full sun. Kids in t-shirts will be asking to go home in 20 minutes. Pack a fleece or windbreaker for every person regardless of what it looks like at the trailhead.
Planning
Parking fee is $8 per car at East Peak, Pantoll, and Bootjack lots; free at Rock Spring and some roadside pullouts along Ridgecrest. The park is open 7 a.m. to sunset; cars parked after hours may be ticketed. No advance reservation needed for day use.
Bring: windbreaker for everyone, water (no fountains at East Peak; there are accessible fountains near the East Peak restrooms but confirm before relying on them), snacks, and sunscreen — the summit gets full exposure on clear days. Best months are April through October. May and September hit a sweet spot of lower fog frequency, good wildflower color in spring, and manageable trail conditions. Avoid the summit on clear summer holiday weekends — parking becomes a genuine problem by 10 a.m. Ages 3 to 4 work well for the Verna Dunshee paved loop at East Peak only. Ages 5 and up with regular hike experience can handle the Bootjack and Fern Creek loops. The steep ladder-accessed trail sections below East Peak are not suitable for under 5.
