October 11, 2025, Steep Rocky Trail

Steep in the first part but easy to do in dry weather

A beautiful path, but difficult to park your car because there are just three parking spots, and you can't really turn around to look further. If you find one, take a spot; after all, you're here to walk.

Quiet residential street with bike lane connecting the bike trail that ends at the Camino Alto tunnel with the bike trail over Horse Hill parallel to Hwy 101

This trail runs along part of the Dipsea Trail and heads towards Cardiac Hill. The first section is characterised by a wooden stairway, then the path goes into a lush forest.

The Dipsea trail takes you back to your starting point. Very soon you will find the big trees again.

Very pleasant redwood forest trail along Larkspur Creek. It climbs gently from the dead end of Madrone Avenue to the small falls near the source of the creek.
