The Phoenix Lake - Yolanda Trail - Hidden Meadows Loop is a 5.25 mile route that travels around Phoenix Lake, up and along Bald Hill and back through Hidden Meadows, a grassy flat that draws deer, bobcat, turkey and even the occasional mountain lion

From Phoenix Lake Trailhead, walk Phoenix Lake Road to the Phoenix Lake Dam (.25 miles : 230'). Follow signs for Lake Lagunitas up the north shore of Phoenix Lake.

Turn right onto the Yolanda Trail (.75 miles 240'), which immediately narrows and rises through a mix of madrone, live coast oak, black oak and California bay trees.

It climbs steadily and winds under the rocky ridge of Bald Hill, where the valley opens with good views of Mt Tamalpais. The trail is mostly exposed until reaching the highest point on the loop (1.65 miles : 600'). 

The Yolanda Trail dips back into the forest and begins a gradual descent to a major trail split (2.0 miles : 530'). Turn left on the Hidden Meadows Trail, which zig-zags down to Phoenix Creek and into Hidden Meadows (2.5 miles : 295'), a series of grassy glades tucked between a small creek and tree-studded hillside.

The trail runs through a young redwood stand before joining the Shaver Grade Fire Road (2.7 miles : 290'). Turn left onto Shaver Grade Road and keep straight through a major trail junction at 3.2 miles. At 3.4 miles turn right onto the Gertrude Orr Trail (signed Phoenix - Ord Trail). Follow it down and across the creek to the south side of Phoenix Lake. 

The Gertrude Orr Trail rides above the south shore of Phoenix Lake, weaving in and out of the adjacent forest (4.0 miles : 210'). It dead-ends at a fire road (4.5 miles : 215') - turn left onto the fire road back to Phoenix Dam (5.0 miles : 230'). Retrace your steps back to the trailhead to complete the loop (5.25 miles : 130').
