Frequently Asked Questions

How long does it typically take to hike this section of the Old Railroad Grade Fire Road?

This specific Komoot route covers a 3 km (1.9 mile) section of the Old Railroad Grade Fire Road and typically takes about 50 minutes to complete. Keep in mind that the full Old Railroad Grade to Mount Tamalpais' East Peak is much longer and more challenging.

Is this section of the Old Railroad Grade Fire Road suitable for beginners?

Yes, this particular 3 km segment is rated as easy by komoot. While the full Old Railroad Grade is known for its sustained uphill climb and is generally considered moderate to difficult, this shorter route is a good option for those looking for a less strenuous experience.

Where does the trail start and where can I park?

This route begins at the West Blithedale Avenue Trailhead. Parking availability can vary, so it's advisable to check local regulations and arrive early, especially on weekends.

What is the terrain like on the Old Railroad Grade Fire Road?

The trail is a wide fire road, primarily made of crushed rock and dirt. You might encounter some rocky sections. It's generally well-maintained but can be rough in places, so sturdy footwear is recommended.

What kind of views can I expect along the route?

As you ascend, you'll be treated to expanding views. From various points, including near the Old Railroad Grade Trail Gate Overlook, you can often see the Pacific Ocean, San Francisco Bay, the Marin Headlands, and the Golden Gate Bridge on clear days.

What is the best time of year to visit this trail?

Spring and fall generally offer the most pleasant hiking conditions with mild temperatures and clear skies, providing excellent visibility for the panoramic views. Winter can be beautiful but may bring rain and cooler temperatures, while summer can be warm and dry.

Does this trail intersect with other well-known paths?

Yes, the Old Railroad Grade Fire Road is a major artery on Mount Tamalpais. While you'll be primarily on the Old Railroad Grade Fire Road for this route, it also briefly overlaps with sections of the H Line Fire Road and the Tamelpa Trail.

Is the Old Railroad Grade Fire Road dog-friendly?

Dogs are generally allowed on fire roads within the Mount Tamalpais Watershed, but they must be kept on a leash at all times. Always check for any specific signage or updated regulations before your visit.

Do I need a permit or pay an entrance fee to hike here?

Are there any notable historical features along the Old Railroad Grade Fire Road?

Yes, the trail follows the exact route of the historic 'Crookedest Railroad in the World,' which operated from 1896 to 1930. You can still see evidence of this past in the carved-out hillsides and the consistent grade designed for the railway. The West Point Inn, though not directly on this short segment, is a significant historical landmark further up the full grade.

What's an insider tip for hiking the Old Railroad Grade Fire Road?

While this Komoot route is an easy introduction, be aware that the Old Railroad Grade is famous for its continuous, steady uphill climb if you decide to tackle the full route to the summit of Mount Tamalpais. It's a great way to gain elevation with a consistent grade, but it requires sustained effort. For this shorter segment, simply enjoy the views and the historical path.
