From the parking lot, cross a short bridge to walk past the nature center/bathrooms, then downhill to cross Arastradero Road. Juan Bautista de Anza Trail begins on the other side of the road. It is a wide fire road that runs parallel to the creek and crosses it at a bridge. After the crossing, the path narrows and meanders in a little hilly region, then widens as you approach the lake. At the lake, the trail junctions with Paseo del Roble Trail, which is equally wide. Turn left to take Paseo del Roble, then follow the narrow side trail in a few hundred feet to the right, heading down to a lake’s beach. This is a great place to view wildlife and in the wet season, a small creek feeds the lake from this area. This is a great break spot.
From the Lake, return to Juan Bautista de Anza Trail and turn left to continue down it. In a few hundred feet, there is a junction with Arastradero Creek Trail.
Stay right to continue down Juan Bautista de Anza Trail, following it until it narrows significantly, just after it comes close to Arastradero Road. There is a gate here and the path eventually ends. Return back the way you came.
