    Hiking

    Homestead Valley Trail leads downhill a few yards off this big Trailhead parking at the intersection used as a key meeting place by many hikers and bikers, some dropping down to the bay, others over to Muir Woods when that National Park parking is overflowing on Summer weekends

    This "Four Corners" intersection on the saddle of Panoramic Highway is the transition for Sequoia Valley Rd crossing over to the Pacific side into Muir Woods Rd. There are also three trails arriving from the Bay side at this point. The views reach from the Bay on one side to the Pacific Ocean on the other.

    The Old Mine Trail (lower) – Coast View Trail loop offers a rewarding mountain biking experience near Muir Woods, taking you through dense redwood forests and along open ridge lines. You'll find a mix of singletrack and fire roads, with the Coast View Trail providing stunning vistas of coastal hillsides and the ocean. Be prepared for challenging sections, including steep climbs and eroded, rutted descents that demand good bike handling skills.

    This moderate 15.8-mile (25.4 km) route involves a significant 2169 feet (661 metres) of elevation gain, typically taking around 2 hours and 29 minutes to complete. While mountain biking isn't allowed inside Muir Woods National Monument, this loop provides access to similar natural beauty in adjacent parks. Always check trail conditions, as erosion on the Coast View Trail can make for a tougher ride.

    This area is celebrated for offering some of the best California redwoods, alongside bay trees and epic ocean views. The varied terrain, from gentle singletrack to fire roads with 12% grades, ensures a dynamic ride. It's an excellent choice for mountain bikers seeking a workout with a scenic payoff, but be aware that some parts may require pushing your bike due to technical challenges.

    The Coast View Trail – Golden Gate Bridge loop from Castro offers an incredibly diverse and challenging mountain biking experience, taking you from urban San Francisco to the dramatic coastal bluffs and open ridges of Mount Tamalpais. You'll encounter largely singletrack terrain on the Coast View Trail, which is known for its stunning panoramic ocean views and beautiful coastal hillsides, making it a classic XC singletrack. Be prepared for sections with surface erosion, deep ruts, and rocks, especially on descents where you'll need constant braking and high alertness.

    This extensive route, covering 48.8 miles (78.6 km) with 4431 feet (1351 metres) of elevation gain, is a difficult ride that typically takes around 5 hours and 53 minutes. Connecting these distinct areas means you should anticipate significant road riding sections to link the different geographical zones. The Coast View Trail is a popular multi-use trail, so be aware of hikers, particularly during peak times like weekends. An early start is highly recommended to complete this demanding loop.

    While the Coast View Trail is a highly regarded "must-do" for mountain bikers in the Mount Tamalpais area, its integration into a loop from Castro across the Golden Gate Bridge creates a unique, very extensive adventure. This combination showcases some of the best mountain biking and scenic viewpoints the region has to offer, including glimpses of the San Francisco Bay and potentially redwood forests. It's a ride for those with good fitness and advanced riding skills, promising a memorable journey through iconic Northern California landscapes.
