Getting there:

• From northbound US 101 in San Francisco County, cross the Golden Gate Bridge and exit at Alexander (the first exit past the view point turnoff). After about 0.3 mile, turn left onto Bunker Road. There is a one-way tunnel which cuts under 101, and you may need to wait up to 5 minutes for your turn to travel through it (this is a great opportunity to put on sunscreen). From the other side of the tunnel, drive about 3 miles on Bunker Drive to the trailhead at the end of the road.
• From southbound US 101 in Marin County, exit Sausalito (the last exit before the bridge). Drive uphill on Conzelman Road, then turn right onto McCullough Road. Descend on McCullough to a junction with Bunker Road, and turn left. Drive west on Bunker to the trailhead at the end of the road.

Trailhead details:
Plenty of parking in lots and on the side of the road. No entrance or parking fees. Wheelchair-accessible restrooms at edge of parking lot. There are handicapped-designated parking spots, but the trails are not wheelchair accessible. No maps available at trailhead. There is a map at the start of the Miwok Trail, about 1 mile from the trailhead. If you want to pick up a map before you start hiking, stop at the Visitor Center on the way to the trailhead: from the Headlands side of the tunnel on Bunker Drive, drive about 2 miles and bear left onto Field (just before you get to the lagoon). Make the first right into the Visitor Center parking lot. Muni bus line #76 services this trailhead via Bunker Road (Sundays and major holidays only): visit the Transit Info website for details.

Gas, food, and lodging:
Gas, restaurants, and stores about 6 miles north in Marin City. There are a few camping options in the Headlands, including small camps at Kirby Cove and Bicentennial.

Dogs are permitted on some Headlands trails (they are allowed on every trail on the hike featured on this page); ask the staff at the Visitor Center for current information, or check the Headlands map on the link below.
