Irving Trail Junction
The junction for the Irving Trail is on the northerly uphill side of the Cross Marin just east of a bridge. Also at this junction is a service road down to the highway.
Continuing on the Cross Marin Trail will take one over a bridge built on the footings of the old railroad and across Lagunitas Creek. It services the southerly side of the state park.
For no other reason than to avoid pavement and crossing Sir Francis Drake HWY later, this walk will have us take the Irving Trail on the northerly side of both Lagunitas Creek and the highway.
The Irving Trail winds along the lower slope of Barnaby Peak and through a series of heavily forested gullies.
If you get lost and cross the bridge, do not worry-the route is quite nice and will get you back to the Park Headquarters, campgrounds, and ultimately, your car.
