Quick Facts

Parking - Auto, Trailhead

Located outside of Point Reyes National Seashore in the Lagunitas area, this flat and wide gravel trail (with some paved sections) that parallels Lagunitas Creek and Sir Francis Drake Boulevard is a great family-friendly outing. It is also an easy bike path with an almost imperceptible grade. This trail goes in and out of the shade through Douglas fir and redwood groves and in the winter, salmon may be seen spawning in sections of Lagunitas Creek by Samuel P. Taylor State Park. On-leash dogs and horses are allowed on this trail.  

This 3.9 mile out-and-back trail is also known as the Sir Francis Drake Bikeway, and is built on the old roadbed of the former North Pacific Coast Railroad.
