Be aware that the visitor center for the lighthouse is only open Thursday through Monday, from 10 a.m. to 4:30 p.m.
Run along the rocky coastline of Point Reyes on a paved path for a little over 1/2 of a mile to reach the famous Point Reyes Lighthouse. Along the way you'll see a visitor center for the lighthouse. After you've learned all about the lighthouse and taken in all the views of the scenic coastline you can return back to the parking area the way you came.
