McKenzie Pass and Fourmile Butte Loop

This route is designed for touring bicycles and primarily follows the challenging and scenic McKenzie Pass Highway (Oregon Route 242). While the tour name includes Fourmile Butte, it's important to note that Fourmile Butte itself is primarily known for horse riding trails and is not typically integrated into a paved touring cycling loop with McKenzie Pass. The main cycling experience will be on the historic McKenzie Pass Scenic Bikeway, offering significant climbs and dramatic landscapes.

The McKenzie Pass Scenic Bikeway is considered a challenging ride, suitable for experienced cyclists. It is 100% paved, featuring a substantial elevation gain of approximately 2,365 feet (721 meters) with a maximum grade of 7.2%. The climb includes a main ascent of 5 miles with a consistent pitch of around 5-7%. The route follows a winding, historic wagon road, offering exhilarating descents with switchbacks.

The best time to cycle the McKenzie Pass Highway is typically from mid-June through mid-November. A unique opportunity exists in the spring, from mid-May to mid-June, when the road is closed to motor vehicles but often clear enough for cyclists as the snow melts. This allows for several weeks of traffic-free riding, offering an exceptional experience.

The McKenzie Pass and Fourmile Butte Loop is located within the Deschutes National Forest. While there are no specific permits required for cycling the McKenzie Pass Scenic Bikeway itself, some trailheads or recreation sites within the National Forest may require a recreation pass (such as a Northwest Forest Pass or America the Beautiful Pass) for parking. It's always a good idea to check the specific trailhead regulations before you go.

The route offers a dramatic transition in landscapes. Highlights include cycling through hay meadows and diverse forests, observing the differences between the 'dry side' and 'wet side' of the Cascades. A major highlight is the 2,000-year-old lava flow creating a stark 'moonscape' at the summit. From Windy Point, you'll see views of Mt. Washington and the lava flow. At the summit, the Dee Wright Observatory, built from local lava rock, provides 360-degree panoramic views of surrounding mountains, including the Three Sisters and Mount Jefferson on a clear day.

If starting from Sisters, Oregon, you can find parking in town before heading out on the initial gentle stretch of the McKenzie Pass Scenic Bikeway. Specific trailhead parking for the McKenzie Pass Highway is available at various points, but it's advisable to check local resources for the most current parking options and any potential fees.

While dogs are generally allowed on leash in the Deschutes National Forest, cycling the McKenzie Pass Scenic Bikeway with a dog can be challenging due to the significant climbs, descents, and potential for traffic (when open to vehicles). If you plan to bring a dog, ensure they are well-conditioned and that you have a safe way to transport them, especially on the paved sections. Always keep them on a leash and pack out all waste.

Yes, the route primarily follows the McKenzie Pass Highway, which is part of the McKenzie Pass trail (61% of the route). It also includes sections of the TransAmerica Trail (Oregon) and various Forest Roads. A small portion of the route also touches the Metolius-Windigo Trail, which is more commonly associated with horse riding and hiking.

Given the challenging nature and potential for remote sections, pack essentials like plenty of water, high-energy snacks, a repair kit for your bicycle, appropriate layers of clothing for changing weather conditions (especially at higher elevations), sun protection, and a first-aid kit. Cellular coverage is limited along the McKenzie Pass Highway, so a map and navigation device are highly recommended.

The town of Sisters, Oregon, located at the eastern end of the McKenzie Pass Scenic Bikeway, offers various amenities including cafes, restaurants, and accommodation options. Once you begin the climb on McKenzie Pass, amenities become very scarce, so it's best to stock up on supplies before starting your ride.

The Dee Wright Observatory is a unique structure built from local lava rock at the summit of McKenzie Pass. It's definitely worth visiting. From its vantage point, you can enjoy 360-degree panoramic views of the surrounding volcanic landscape, including the Three Sisters mountains, Mount Jefferson, and the vast lava flows. It's a fantastic spot for photos and to learn about the area's geology.
