If you're looking for a mountain bike ride that truly tests your mettle while delivering incredible coastal panoramas, the Devil's Slide – Ace Trail loop from San Bruno is a solid choice. This difficult 28.3-mile (45.5 km) route packs in 3661 feet (1116 metres) of elevation gain, taking roughly 3 hours and 55 minutes to complete. You'll start with the smooth, paved Devil's Slide Trail, offering expansive views of the Pacific Ocean and the dramatic coastline. But don't let that fool you; the Ace Trail segment quickly ramps up the challenge, plunging you into rugged, technical terrain with demanding climbs and descents, often around prominent bluffs and towards Montara Mountain. Expect a varied experience, from easy cruising to strenuous singletrack.
This loop is best tackled by experienced mountain bikers with good fitness, as the 'difficult' rating is well-earned, especially on the Ace Trail. Starting from San Bruno means you'll be connecting to a wider network of trails, so plan your route carefully to make the most of the diverse terrain. While the Devil's Slide portion is accessible, the Ace Trail introduces significant technical challenges, including rocky sections and steep ascents. Always check weather conditions, as the coastal exposure can mean strong winds or fog.
The Devil's Slide Trail itself has a fascinating history, converted from a landslide-prone section of Highway 1 into a multi-use path, offering safe access to a visually dramatic stretch of coastline. This repurposing allows you to experience unique geomorphology and stunning views that were once only for cars. The combination of this historic, scenic path with the raw, challenging Ace Trail creates a truly distinctive mountain biking adventure in the San Bruno area, blending history, nature, and adrenaline.
