Starting from the southernmost part of the county, the Marin Headlands offers countless long and short loops and trails. These two dog-on-leash-friendly routes both start from the Rodeo Beach parking lot at Fort Cronkhite.
Old Bunker Road Loop (1.5 miles)
This is a scenic, mostly paved road that circles the Rodeo Beach area. Start at the Coastal Trail trailhead at the north end of the Rodeo Beach parking lot. Wind up the fairly steep fire road, staying to your right. The trail flattens out and intersects with Old Bunker Road. Keep right on Old Bunker as it circles back toward the buildings via a metal gate. Continue on the paved road to Kirkpatrick Road, which leads back to the parking lot. The road has been damaged by erosion and earthquakes but can still be navigated by a “sport utility” (jogging) stroller, though not by a wheelchair.
Hill 88 Loop—Coastal Trail to Wolf Ridge to Miwok Fire Road (5.1 miles)
This longer, more strenuous hike circumnavigates Hill 88 above Rodeo Beach. Start at the Coastal Trail trailhead at the north end of the Rodeo Beach parking lot. Wind up the fairly steep fire road, staying to your right. Where the trail intersects with Old Bunker Road, veer to the left and look for the continuation of the trail on the right, in the middle of a small grove of cypress trees. The ascent is steep, with a rocky staircase. Veer right at the top and continue on the paved road to your left.
Just before the summit, go right onto the Wolf Ridge trail, which continues across the back side of Hill 88, and right again on Miwok Fire Road. Head down to the floor of Gerbode Valley, and keep to the right. Miwok eventually hits Bunker Road. Cross the road, and walk along Rodeo Lagoon back to the parking lot.
South on Hwy 101 to the Sausalito exit. Left onto Lateral Rd, right on Conzelman Rd, right at McCullough Rd, left on Bunker Rd. Veer left toward Fort Cronkhite. Park at the Rodeo Beach parking lot; trailhead is at the north end.
