The Sandy Ridge Trail System is a mountain biker's paradise with over 15 miles of flowing single-track trails of all difficulty levels on the lower slopes of Mt. Hood. They range in length from 3/4 of a mile to 5 miles and the courses wind through glorious forest and along sparkling streams, so you can take in a bit of scenery while enjoying the ride.
It was designed to provide mountain bikers with a high quality experience and the Bureau of Land Management (BLM) continues to invest in numerous upgrades and expansions due to the popularity of the trails. They have increased the parking situation dramatically, moving from 36 standard parking spaces to 151 large standard spaces plus 6 large vehicle spaces for RV, trucks with trailers or converted vans. They have added four designated event locations, two designed for bike demos and two that will have power and water which can accommodate food trucks. Additionally, a new vault restroom, new changing rooms, a bike wash station, a host site, new security system with cameras over the parking area, a bike hub/bus stop, 10 tailgate bump-outs/picnic sites and an interior trail that will be designated for families and children.
BLM is currently in the process of determining whether to add an additional 2-mile long ex-fill trail to the trail system that would be more of a dark blue trail for the seasoned riders. This would help to prevent high level enthusiasts from running into less experienced riders on the existing trails.
