El Corte de Madera Creek Open Space Preserve

El Corte de Madera Open Space Preserve, known to locals as Skeggs (after Skeggs Point), is a 2,908-acre (1,177 ha) open space preserve in San Mateo County, California.

[2] A portion of the Bay Area Ridge Trail runs through the park.

[5][6] Prior to its acquisition by the Mid-peninsula Regional Open Space District (MROSD), the area was also used by a local motorcycle club (PITS); who built an extensive network of trails in addition to the old logging trails.

ROMP also grew into today's (2025) Silicon Valley Mountain Bikers) advocated for the preservation of certain trail features which made them so interesting for mountain bikers.

These advocacy efforts resulted in mountain bikers building the new "Leaf Extension" trail, and the original "Leaf" trail being preserved at the original 3ft width.
