Slacker Hill is one of those insider locations trailheadyou'll be glad to have in your hiking arsenal. Although the trailhead is a stone's throw from one of the most heavily-visited tourist spots in the Bay Area (the Golden Gate Bridge overlook on Conzelman) trails are usually almost empty and a short steep climb leads to a vantage point with exceptional views.
     From this trailhead you could make a 3 mile loop of the roadside path along Conzelman combined with Coastal Trail. Even though the roadside path abuts Conzelman, views to the Golden Gate should provide some compensation. gate on Coastal TrailOr take Coastal Trail to the west, drop down into Rodeo Valley and climb on Rodeo Valley Trail to SCA Trail. The return route passes over the Baker-Barry Tunnel before skirting Slacker Hill to the trailhead. This option is about 4.6 miles.
     My favorite hike at Slacker Hill is the short and sweet climb to the hilltop. It's gorgeous (and a bit spooky) in fog, but chilly, so dress accordingly. Start at the parking lot and follow the narrow path (unsigned here) departing on the same side of the lot as the pit toilet.trail to Slacker Hill  Lush coastal scrub lines the trail, and the often moist weather seems to coddle monkeyflower, lizardtail, and fennel into extended blooming seasons. After 300 feet, carefully cross the street, then continue uphill on Coastal Trail. The gated fire road begins a sharp and rocky ascent -- look uphill to the right at the huge boulder hanging off the hillside. A few willows initially line the fire road on the left. Coastal Trail climbs through dense coastal scrub including coyote brush, bush lupines, sagebrush, poison oak, and monkeyflower. view from Slacker HillOld man's beard, a lichen, grows conspicuously over many branches of coyote brush -- it's as is if the bushes are wearing pale green fuzzy sweaters. Annual wildflowers begin to bloom about March here, with white zigadene and purple bluedicks usually the first to show. Flowers continue to brighten the hillsides along the trail through September (some, like paintbrush, linger into November). After climbing about 1/4 mile, you'll reach a signed junction. Turn right, following the sign to Slacker Ridge.returning downhill from Slacker Ridge
     The climb continues, albeit at a slightly easier pace. At about 0.4 mile the official trail bends right (a path to the left, to the other "peak" on Slacker Ridge is closed) and makes a final push to the top. Native bunch grasses are very common along this stretch, mixed through coyote brush, monkeyflower, blackberry, and ferns. At 0.5 mile, the trail ends at a flat treeless hilltop. The views are spectacular in every direction; the Golden Gate is particularly striking down to the south. What a great place to watch the sunset (just don't wait too long to head back downhill)! When you're ready, retrace your steps back to the trailhead.
