The round trip to Reynolds Peak generally takes hikers between three to four hours to complete. This duration accounts for the sustained elevation gain and technical sections of the trail.
The trail starts by traversing east before bending north as it ascends the canyon. The path to Dog Lake is well-marked. Beyond the lake, the ascent to Reynolds Peak involves a fainter track that can be overgrown in spots. Expect technical singletrack with roots and embedded rocks, and potentially steep, slippery sections with log water-bars. The lower half is heavily forested, while the upper half opens up to meadows.
This trail is officially rated as 'Difficult' or 'Hard' by various sources, and categorized as T3 Demanding Mountain Hiking on the SAC scale. While the views from the summit are rewarding, the sustained elevation gain and technical terrain make it more suitable for hikers with some experience rather than absolute beginners.
Parking for the Mill D North Fork Trail is available at the trailhead located in Big Cottonwood Canyon. It's advisable to arrive early, especially on weekends, as parking can fill up quickly. For more detailed information on access, you can check resources like the USDA Forest Service website.
No, dogs are generally prohibited on this portion of the trail because it originates from Big Cottonwood Canyon, which is part of the Salt Lake Watershed. Dogs are only allowed if accessed from Mill Creek Canyon, but this specific route starts in Big Cottonwood Canyon.
Hikers are treated to very scenic views throughout. You'll pass the tiny and picturesque Dog Lake, and as you gain elevation, you'll get 'eye-popping views' of the Wasatch peaks. The summit of Reynolds Peak offers wonderful panoramic vistas of Big Cottonwood Canyon, including Gobblers Knob and Mount Raymond, and the high peaks of the Twin Peaks Wilderness Area to the south. During summer, beautiful ferns and wildflowers are also abundant.
The best time to hike this trail is typically during the summer and early fall months when the snow has melted, and wildflowers are in bloom. The area is also popular for winter activities like snowshoeing and cross-country skiing, but the hiking route transforms into a ridgeline tour during those months.
Generally, there are no specific permits or entrance fees required for day hiking on the Reynolds Peak via Mill D North Fork Trail within the Mount Olympus Wilderness. However, it's always a good idea to check the latest regulations with the U.S. Forest Service before your trip, especially for group sizes or overnight stays.
Yes, the route primarily follows the Mill D North Fork Trail. It also briefly intersects with sections of the Desolation Trail and the Mill D North Fork Connector Trail.
Absolutely. Key landmarks include the picturesque Dog Lake, which is a popular stop. The ultimate viewpoint is the summit of Reynolds Peak itself, offering expansive panoramic views of the surrounding Wasatch Range and canyons. Along the initial ascent, you'll also get scenic views looking back towards the Solitude area.
While the overall trail is rated difficult, the climb from Dog Lake to Reynolds Peak is often described as 'not-too-difficult' given the rewarding summit views. It involves finding a faint track on the south side of the lake leading up the north ridge. This section can be overgrown but offers a direct path to the exceptional panoramic vistas.
