This seems better than there isn't. Thanks for the help.
Your Most Welcome,
Here's the Willow Creek specific access info:
fwiw, I've never been asked in 40+ MB rides within WC for my permit-access pass,
Regardless, even if unable to attend the scheduled orientation, please $$ support org's that include MB riding.
Willow Creek roads & trails connect with adjacent State Park lands, allowing users to hike or ride the 7+ miles from Duncans Mills to Shell Beach - all on State Park land.
Due to the ongoing State Parks budget crunch, LandPaths has been asked to continue providing access at Willow Creek through a Permit-for-Use program (started in 2005). A permit for hiking, biking, and horseback access is issued after a 1-hour orientation on the property. Read on for details about this innovative program and how you can help keep it going.
There is some really good road rides in the area if you are into that sort of thing...
Seriously, the road riding is incredible even if it's not generally your thing. Check out Coleman Valley Road.
