Blithdale Loop

While some sections, like parts of the historic Old Railroad Grade, are quite easy, the Blithdale Loop itself can involve moderate to steep ascents and descents, offering a good workout. The trail is generally considered easy, but be prepared for varied terrain including some 'roller coaster uphills and downhills' on fire roads and narrower paths with roots and rocks.

The Blithdale Loop can be accessed from several points, with a common starting point being the Huckleberry Trailhead. Specific parking information for the Blithedale Summit Open Space Preserve can often be found on local Marin County visitor websites or park service pages.
