Backtracking, at 5.04 miles, where the paved trail turns back inland, take the dirt road straight ahead. The road runs between the Bay and a wide, winding slough. Along the slough are old 3-sided concrete structures. The muddy and rocky shoreline turns into a wide sandy beach here. A beach of this size and quality is rare on the Bay, but it's likely to be deserted.
Driftwood lines the beaches.
The sandy beach turns into thick stands of grass, sandbars, and mudflats closer to the mouth of San Lorenzo Creek, making further travel along the shore difficult. The dirt trail turns inland as it follows the slough. At 5.35 miles, it deadends at the slough. Across the slough is the end of the trail seen earlier at 2.12 miles. Narrow footpaths lead farther down the slough, but the ground may be muddy.
