El Corte de Madera Creek

  • Methuselah Trail, from Giant Salamander Trail to South Leaf Trail, is CLOSED to equestrians due to trail damage.

The trail between the Oljon junction and Highway 35 has been replaced with a newly constructed section 1.3 mile section of the Oljon Trail, connecting to Springboard. This final portion of the watershed protection program reduces the need for preserve visitors to access Highway 35 during their visit and adds over 2,000 feet of new single track to the existing trail network.
