Go over the San Rafael/Richmond Bridge and follow the signs to Sir Francis Drake Blvd.

Go West on Sir Francis Drake Blvd. After passing the Larkspur Ferry Terminal you’ll pass under route 101.You will then drive through a number of East Marin suburbs. After passing through the redwoods of Samuel P. Taylor Park you will arrive at the village of Olema. The distance from highway 101 to Olema is 20 miles.

Sir Francis Drake Blvd dead-ends into Route One/Shoreline Hwy. Turn right and proceed north approximately two miles.

Make a left turn just before the green bridge, towards "Inverness" (this is Sir Francis Drake Blvd., but the road sign is often missing). Continue a little over one mile, and look for a green city sign saying: Inverness Park.

Just around the next bend, you'll be taking a left onto Vallejo Avenue. Busy Bee Bakery and the Inverness Park Grocery/Perry's deli are located on the corner. The Blackthorne Inn is located at 266 Vallejo Avenue almost at the end of the road on the right hand side. We have a fairly steep driveway, with five parking spots available, including the steep paved area.
