Loma Prieta Grade Professional Guide
Detailed Trail Description from our Guidebook
"The trees within the Forest of Nisene Marks are so thick and the environment seems so pristine that it’s hard to fathom the rail-trail upon which you tread was once part of an extensive logging operation in the Aptos Creek Canyon. The rail trail is relatively steep, and completing the entire loop will take most of a day.
In the Forest of Nisene Marks, nature proves that it can renew itself. The original redwoods and Douglas firs that grew here, thriving on moisture from the nearby Pacific Ocean, were extensively logged in the early 1900s, but you’d never know it now. The evergreens, along with oaks, madrones, and bays, have grown back with a vengeance, creating a jungle that envelops park trails in a translucent green light. This benevolent light even shines on the trail that runs along the grade of the railroad that was used to haul the ancestor trees down and out of the canyon."
