The Adobe Creek Trail departs the parking lot in Byxbee Park and meanders its way along Adobe Creek, Charleston Slough, Matadero Creek, and the Mayfield Slough providing you amazing opportunities to see a wide variety of water fowl throughout the year.
The path starts as a wide gravel trail with marshlands on the left and the Byxbee Park Hills on the right. At roughly half a mile, the trail turns to the right and crosses a bridge so that the South San Francisco Bay is on your left. Be on the lookout for windsurfers enjoying themselves out in the bay while various types of birds can be seen along the shores of Adobe Creek. As you approach the 1 mile mark, a large group of sea gulls can be seen nest and resting on an island in Adobe Creek on right. If the tide is low, various species of birds can be seen feeding in the mud along the trail. At 2.25 miles, be on the lookout for Pelicans resting in Adobe Creek on the right side of the trail.
At roughly the 2.5 mile mark, the Bay Trail
to Shoreline breaks off to the left while the Adobe Creek Loop turns from gravel to concrete and approaches Bayshore Road. As you pass 3 miles, the trail crosses Adobe Creek and runs parallel to Highway 101 and Bayshore Road for approximately 3/4 of a mile. The trail crosses Matadero Creek and turns back to gravel as it meanders through the Renzel Marsh and follows Matadero Creek. At 4 miles, the trail takes a hard right turn as it continues to follow Matadero Creek on the right side of the trail while the Byxbee Hills are back on your left.
Be on the lookout for rabbits, who scurry away when they hear you coming. Herons, Canada geese, and various species of ducks can be seen in Matadero Creek/Mayfield Slough. At the 5.5 mile mark, you arrive back at the junction with the Adobe Loop Trail
that you passed earlier. Take a left to make your way back to your car and the parking lot which is 1/4 of a mile from the junction.
If you want a little sting at the end, cut up over the hill and enjoy a nice view of the surrounding Bayshore.
Watch out for the Canadian geese that can be rather protective of their space.
