Railroad Grade at Fern Canyon & Summit

Highlight • Trail

Uphill from this intersection a portion of the Railroad Grade has been taken over by Fern Canyon Rd after the Mt Tam railroad closed. A short distance uphill on pavement brings you to the end of Fern Cyn. A bit before the end the Railroad Grade gravel forest road splits off again to the right. The Temalpa Trail that joins here is steep with stairs, not open to biking.

Old Railroad Grade Trail (upper half) — Mt Tam

Highlight (Segment) • Trail

Old Railroad Grade trail follows the route of the railroad that reached the peak of Mount Tam from Mill Valley (and a spur to Muir Beach) between 1896 and 1930. This segment starts about mid-mountain at the site of an old station (notice the concrete "sidewalk" on the side of the trail), at the intersection with Gravity Car Trail and Hoo-Koo-Ee-Koo trail, just above the Double Bowknot (a series of four hairpin curves of the old railroad). Since this used to be a railroad, it has a very steady average grade of around 6%, making it easy to climb up on a bike. About 2 miles from the old station platform the trail passes West Point Inn ( komoot.de/highlight/215020 ) , with snacks, picnic tables and restrooms (also offering romantic cabins with killer views across the whole bay).
