Muir Beach / Muir Woods Closure Information – December 2014 – March 2015

Rainstorms on December 11, 2014 caused a section of CA-1 (SR-1) to collapse between Muir Beach and Panoramic Drive.

This section of road is featured in our trail and video “The Three Amigos“.

As this route of return is no longer available, this closure affects the ride back to Sausalito from Muir Woods and Stinson Beach.

From Muir Woods, you have the option of climbing back up Muir Woods Road or heading to Stinson Beach and climbing back via Panoramic Highway, the opposite direction of our Dog Days trail.

Your other options are to continue North on CA-1 and 1) attempt the climb up Fairfax Bolinas Road to West Ridgecrest and return via the latter half of Alpine Damn Loop

Or 2) go toward Point Reyes and return via Sir Francis Drake Blvd to Fairfax.

Construction is expected to continue through March 2015. See for the most up-to-date information on the closure and construction.

At this time we do not advise going to Muir Woods or Stinson Beach unless you are a very strong climber or are prepared for a 60+ mile ride.

Update: Marin Headlands Closure Information

NOT OPEN YET! One more month before the descent down Hawk Hill is open to bicycles again.

On September 15, 2011 the US Park Service reopened Lower and Upper Conzelman Road to vehicles and pedestrians.

Bicycles are allowed up Lower Conzelman Road to Hawk Hill. But bicycles are still prohibited beyond Hawk Hill due to the repaving of Field Road. The paving of Field Road is expected to be completed between mid- to late- October 2011.

Another option for descending from Hawk Hill is to turn at the roundabout and head down McCullough Road to Bunker Road and back through the tunnel. For more information, see our Marin Headlands route here.
