At 3200 meters (one gets a little complacent with the summit heights!), Mount Royal isn't the largest or most prominent mountain in the Tenmile Range, but it's impressive! It marks the northern end of the range and towers above I-70 to the east, with Frisco forming the base of the western slope. With a wall height of almost 500 meters, it offers plenty of climbing potential—especially used by locals! The path to the top is lined with old mines; apparently, in the past, besides Frisco, there was another town on the slopes of this steep mountain: "Masontown" (founded by General Buford in 1866). Gold and silver were mined here and transported to the mint in Denver. Several avalanches completely destroyed the town in 1912, and we can still see the remains today. Near the summit, the mountain doesn't have to fear comparison with other Alpine peaks. Found by chance—as an alternative to the rain—it was worth it!

The summit is usually clear of snow by mid to late June and offers a great challenge. If you are on the run for the views, the lower trails on Tenderfoot Mountain offer better overlooks.

Dillon is surrounded by several notable peaks. For challenging climbs with rewarding views, consider Mount Royal, which offers dramatic views over Frisco and the Dillon Reservoir, or Buffalo Mountain, known for its difficult approach and expansive views of the Gore and Tenmile Ranges. For slightly less strenuous options with great views, Tenderfoot Mountain provides panoramic vistas of Lake Dillon.
Yes, for a family-friendly experience, the Lakeshore Perimeter overlook is an excellent choice. It's located on the Lakeshore Perimeter Trail, offering views of Lake Dillon and the surrounding mountain ranges. While some peaks are challenging, this overlook provides accessible scenic beauty.
The terrain around Dillon is diverse. You'll find trails traversing cool aspen groves, sagebrush-studded open hillsides, and lodgepole pine stands on mountains like Tenderfoot. Higher elevation trails, such as those on Mount Royal or Peak One, can be steep, rocky, and exposed. Buffalo Mountain is particularly known for its piles of talus and scree, indicating a difficult, rugged approach.
The hiking season generally runs from late spring through early fall. South-facing slopes, like those on Tenderfoot Mountain, are pleasant for early season mornings and evenings. Fall is particularly spectacular for peaks in the Tenmile Range, such as Peak One, due to the changing aspen leaves. It's crucial to be prepared for changing weather conditions, especially in the high country, and to start early to avoid afternoon thunderstorms.
For experienced hikers seeking a significant challenge, Buffalo Mountain offers a rigorous workout with over 3,000 feet of elevation gain on its 12-mile loop. Mount Royal is also a steep and rewarding climb, considered a class 3 scramble in parts. For the ultimate high-altitude experience, the nearby 14ers, Grays Peak and Torreys Peak, accessible from Summit County, present an intense alpine mountaineering goal.
Yes, several peaks provide expansive vistas. From Ptarmigan Peak, you can expect views of various 13,000 and 14,000-foot peaks and small mountain towns.

Yes, the path to the top of Mount Royal is lined with old mines. Historically, a town called 'Masontown' existed on its slopes, founded in 1866 for gold and silver mining. Although destroyed by avalanches in 1912, remnants can still be seen today, adding a historical layer to the challenging climb.
Given the high altitude and variable conditions, it's crucial to be well-prepared.

Sturdy hiking boots are essential for the often rocky and steep terrain. For more challenging routes, navigation tools and emergency supplies are also recommended.
