Thornhill Mountain Biking Trails

Thornhill is a long-established network of mixed use trails in Maple Ridge. Originally travelled by equestrian and then motorized users, as well as hikers, in more recent history the area has seen mountain-bike specific trails developed for riders of all ages and skills. These trails were originally unknowingly unauthorized, but are now 'on the map' and the popularity of the riding area is evident as to how popular the trails have become.

The climb is tame, the descents range from mellow blue, to big and boosty double-black, and all points in between. There is something for everyone at Thornhill.

As this is a multi-use trail network -> PLEASE NOTE: When encountering horses, the MTB rider should yield to the horse rider. Yielding to Equestrians: Bikers often scare horses. We are less familiar to them than hikers, so use caution. We recommend that as you approach an equestrian trail user you call out a friendly greeting from far away. Slow down too. You want to start talking from about 50-75 ft away if you can. Horses spook easily, so try asking how the person on the horse would like you to get by. Would they like you to get off and walk (this is great for horses that are really skittish) or should you pass slowly at the next safe spot? Respect for all trail users creates a healthy trail community.

Look for new signs that have been put in place. These signs have been put in place by the city of Maple Ridge with consultation from the Haney Horsemen Association and the Fraser Valley Mountain Bike Association. You will see signs at the bottoms of the downhill specific mountain trails that say "Downhill biking primary trail Expect to encounter bikes". Signs on very popular multi use trails will say "Shared Trail Expect to encounter horses/pedestrians/cyclists Walking speed only". Signs on long standing equestrian trails will say "Steep narrow trail section Cyclists must dismount and walk bikes" and "Horse Primary trail Cyclists must stop to allow horses to pass". And lastly there will be signs for the east side of the hill that has been built and developed for the hiking community these signs will say "Pedestrian trail only". These trails are still mostly unsanctioned and will be use at your own risk.
