Old Railroad Grade Trail

The Old Railroad Grade, Glen Fire, Smith Ridge & Sunrise loop offers a dynamic hiking experience, combining historical paths with challenging climbs and panoramic vistas. This moderate 4.9-mile (7.9 km) route, featuring 875 feet (267 metres) of elevation gain, typically takes about 2 hours and 25 minutes to complete. You'll traverse wide fire roads, dirt, and gravel paths, with sections like the Sunrise Fire Road presenting notably steep ascents, while others, like the Old Railroad Grade, offer a more gradual, though sustained, climb. Expect diverse scenery, from redwood canyons and chaparral to open grasslands and sweeping Bay Area views.

Planning your visit to this Marin County gem is straightforward, though awareness is key. Street parking is available, particularly near the Glen Drive starting point for the Glen Fire Road, but it's always wise to arrive early, especially on weekends, to secure a spot. The trails are multi-use, so you'll share the path with mountain bikers and horseback riders; courtesy and awareness of other users are essential. While the loop can be enjoyed year-round, spring brings vibrant wildflowers, and clear days offer the best visibility for the expansive views.
