Ripplebrook & Skyline Road loop

This loop is generally considered a difficult gravel ride, requiring very good fitness. While some variations exist for different skill levels, the main route involves significant elevation gain and can be quite demanding. Expect sustained climbs and exhilarating descents.

The loop features a diverse mix of surfaces, including paved, asphalt, and unpaved roads, as well as primitive forest paths, singletrack, and doubletrack. Some sections are smooth, while others can be rough, especially after junctions or on specific trail segments. You'll encounter everything from gradual climbs to steep grades, and both paved and gravel descents.

Riders will be immersed in the deeper zones of the southwest quadrant of Mount Hood National Forest. Key scenic highlights include the tranquil Little Crater Lake, pristine river valleys, and panoramic views of both Mt. Hood and Mt. Jefferson from elevated points like Mt. Lowe. You might also see wildflowers in the spring.

The loop typically starts from the Ripplebrook store. This is a common and convenient starting point for accessing the route.

The best time to ride is generally during the warmer months when snow has melted and forest roads are clear. Spring offers the chance to see wildflowers, while summer and early fall provide more consistent conditions. Always check current trail and road conditions before heading out.

Dogs are generally allowed on trails and forest roads within Mount Hood National Forest. However, they must be kept on a leash, and owners are responsible for cleaning up after their pets. Always check specific regulations for any sections of the route that might pass through designated wilderness areas or sensitive habitats.

While there isn't a specific permit required for biking the Ripplebrook & Skyline Road loop itself, some areas within Mount Hood National Forest may require a Northwest Forest Pass or other recreation passes for parking at certain trailheads or day-use areas. It's advisable to check the Mount Hood National Forest website for the latest information on pass requirements.

Potable water sources are limited along the route, and cell service can be spotty outside of the Timothy Lake area. Riders should be self-sufficient and carry enough water, food, and emergency supplies for the entire duration of the ride due to the remote nature of parts of the route.

Yes, the route incorporates sections of several other paths and roads. Notably, it includes parts of the Cascading Rivers Scenic Bikeway and briefly merges with the Pacific Crest Trail (PCT - Oregon Section F). You'll also ride on significant forest roads like Forest Road 42 and Forest Road 4670.

Given the length and difficulty, you should bring a well-maintained gravel bike, plenty of water, high-energy snacks, a repair kit, navigation tools (GPS device or komoot app with offline maps), appropriate clothing layers, and a first-aid kit. Due to limited cell service, consider carrying a satellite communication device for emergencies.

A significant climb is the ascent up NF 4670 to the 5300 ft summit of Mt. Lowe, which can have grades of 5-10% and transitions from paved to white gravel. For descents, NF 42 is considered one of the best paved descents in Oregon, and there's a flying 9-mile gravel descent to the Collawash river via NF 6350.
