No, this loop is generally classified as difficult or extreme for cycling. It requires a very good fitness level due to significant climbs, including pitches up to 17% grade, and challenging gravel sections. It's best suited for experienced cyclists looking for a demanding ride.
The route is primarily paved, but it includes several miles of light to medium gravel sections, particularly on NF1810 and parts of FR 1828. These gravel portions can be washboardy and may have large potholes, especially on descents. Some roads are narrow and primitive, requiring caution. While climbing the gravel is manageable, descents demand extra attention due to potential hidden potholes in shaded areas.
You can expect to ride through dense, magical woods and enjoy beautiful valley cutaways. The route offers unparalleled views of Mount Hood, especially from roads leading up to higher elevations. The 'back road' (FR 1828) provides a sense of solitude with minimal traffic and glimpses of Mount Hood.
The best time to cycle this loop is typically from late spring through early fall, once the snow has melted and before winter conditions set in. Always check current road and weather conditions before heading out, as some sections can be impacted by snow or heavy rain.
A common starting point is the Lolo Pass Trailhead. Parking availability can vary, so it's advisable to arrive early, especially on weekends, to secure a spot.
While there are no specific cycling permits required for the Lolo Pass gravel loop itself, some areas within Mt. Hood National Forest may require a Northwest Forest Pass or a day-use fee for parking at certain trailheads or recreation sites. It's always a good idea to check the official Mt. Hood National Forest website for the most current regulations before your visit.
Dogs are generally allowed on trails within Mt. Hood National Forest, but they must be kept on a leash at all times to protect wildlife and ensure the safety of other users. Please remember to pack out all pet waste.
Yes, the route briefly intersects with several other paths. You'll find sections that cross the PCT - Oregon Section G, TNT, Forest Road 1800-050, Forest Road 210, and the Pacific Crest National Scenic Trail #2000, among others.
Given the challenging nature and remote sections of this loop, it's essential to be self-sufficient. Pack plenty of water, snacks, a repair kit (including spare tubes, pump, and tire levers), appropriate layers for changing weather, a first-aid kit, and a fully charged phone. A GPS device or a downloaded map is highly recommended due to limited cell service in some areas.
Yes, there's an option to incorporate a detour to Wahtum Lake, which is a remote and beautiful lake mainly trafficked by hikers. This can add to the adventure if you're looking for an extended experience. The route itself also offers a less-trafficked alternative to some highway riding, providing a quiet and peaceful experience through remote roads and shaded forests.
The Lolo Pass gravel loop is approximately 53.5 kilometers (33 miles) long with about 887 meters (2,920 feet) of elevation gain. For an experienced touring cyclist, it typically takes around 3 hours and 38 minutes to complete, but this can vary significantly based on fitness level and stops for scenery.
The Lolo Pass gravel loop is located in a relatively remote part of Mt. Hood National Forest. There are no amenities, cafes, or services directly on the loop itself. It's crucial to bring all necessary supplies, including food and water, for the entire duration of your ride. You'll find services in nearby towns like Sandy or Hood River before or after your ride.
