0.0: Start at the entrance gate. After about 250 feet, you'll arrive at the information signboard and an unsigned junction. Stay to the left on the wide paved path, a Bay Trail segment.
0.1: A dirt path departs to the left. Continue straight.
0.2: A trail breaks off to the right, heading to a picnic area (and the portable toilets). Continue straight on the pavement.
0.2: A trail heads right (the numbered posts and the short loop goes with it). Continue straight.
0.2: A dirt path feeds in from the left as the trail reaches the riprap-enforced shoreline. Bear right and remain on pavement.
1.3: Just past a bench on the left, the paved trail swings left, and a broad dirt trail veers right and uphill. Turn right onto the dirt trail. (This area was under construction in July 2002, and trails may be rerouted.) A trail heads left. Stay to the right. After a few more steps, ignore a path to the right.
1.4: T junction. Turn right, and then continue straight past a trail heading left. Stay on this wide trail -- you'll pass numerous other options on both sides of the trail.
1.8: Junction. Stay to the left.
1.8: Junction. Veer right (you should notice planted vegetation on the right, and the portable toilet may also be visible).
1.9: At the next two junctions turn left, and then just before an ugly industrial plant at the park property, turn right.
2.1: Information signboard, again, and the hike's first junction. Retrace your steps back to the trailhead.
2.1: Back at Neptune.
From I 880 in Alameda County, exit Marina Boulevard West (exit 33b). Drive west on Marina about 1.2 miles, then turn right onto Neptune. Drive about 0.6 mile on Neptune, to roadside parking at the end of the road.
