Beginning at the gate at Lake Road, head down the wide fire road. You’ll see a bench where the trail forks; turn left towards the lake (right takes you down John Brooks Trail, which gets steep in spots, but does lead to two nice vista spots higher up). After the lake comes into view after about 0.6 miles, look for a wide trail to access it, turning to your right. Check out the lake.
Continue along the fire road farther, until you reach the end of the open space trail, at Lyall Way. Return the way you came.
