One Tam: many ways to give back to the mountain that gives us so much

Deer Park Fire Road & Dipsea Trail Rehabilitation

The braided alignment of the storied and much-loved Dipsea Trail and Deer Park Fire Road weave in and out of Mt Tamalpais State Park and Muir Woods National Monument. Both eventually meet Redwood Creek, which is home to threatened steelhead trout and endangered coho salmon. 

The Deer Park Fire Road is one of the leading sources of fine sediment into the creek, smothering the gravelly streambed where these fish lay their eggs. The fire road’s erosion and drainage issues have also earned it the dubious distinction of being the most expensive to maintain in the Redwood Creek watershed.

Because the Dipsea Trail and Deer Park Fire Road are so intertwined, a holistic rehabilitation approach is necessary to avoid simply shifting the problems from one to the other.

This project will restore the natural drainage patterns throughout the trail corridor, reducing the sediment flowing into Redwood Creek as well as creating safe and sustainable trail alignments to protect natural resources and visitor access well into the future. Durable stone stairs will also replace decaying wooden ones along the Dipsea Trail in the classic Civilian Conservation Corps style so characteristic of Mt. Tam.
