Highland Mary Lakes Trail

The trailhead is accessible from Silverton, Colorado. While a 2WD vehicle can get you part of the way, the last stretch often requires a high-clearance 4WD vehicle. If you don't have a 4WD, you can park at a lower area and hike an additional mile to reach the official trailhead.

The trail starts with a climb through forests and meadows, often alongside waterfalls. As you gain elevation, it becomes more rugged, with steep ascents over rock outcroppings and even a field of basalt boulders. You'll encounter minor creek crossings, which can be swift in early summer. The forest eventually gives way to open, high-altitude subalpine meadows and alpine tundra, particularly vibrant with wildflowers in late summer.

The hiking season is relatively short due to snow. Snow often persists until mid-July and returns by mid-September. The best time to visit is typically from mid-July to early August, when the subalpine meadows are spectacular with waist-high wildflowers.

The Highland Mary Lakes Trail is located within the Weminuche Wilderness. While there are generally no specific permits required for day hiking, standard wilderness regulations apply. These include prohibitions against camping on lake shores or within 100 feet of any water source, and restrictions on motorized or mechanized transport (like mountain bikes) and drones. Always check the latest regulations with the Forest Service before your trip. You can find more information on the USDA Forest Service website.

You'll experience stunning alpine scenery, including picturesque waterfalls along Cunningham Creek. The route offers breathtaking views of the glistening Northern Highland Mary Lake and Highland Mary Lake, as well as Verde Lakes. You'll also get magnificent vistas of the Grenadier Range, featuring West Trinity, Vestal, and Arrow Peaks, and views of peaks above Deep Creek Valley and Spencer Basin.

This trail is generally rated as moderate-strenuous to advanced due to significant elevation gain, especially in the initial 1.7 miles, and rugged terrain. While experienced hikers may find it manageable, beginners or families with young children might find the ascent and rocky sections quite demanding. It requires a good level of fitness.

As the trail is located within the Weminuche Wilderness, dogs are generally allowed but must be kept under control, preferably on a leash, to protect wildlife and ensure a pleasant experience for all hikers. Always practice Leave No Trace principles, including packing out all pet waste.

Yes, the trail offers flexibility. You can complete it as an out-and-back, or extend your hike by connecting with segments of the Continental Divide Trail (CDT) and the Cunningham Gulch trail, which is also part of the route. These connections can offer extended views and a different experience.

Water is available from creeks and lakes along the trail. However, purification is strongly recommended before drinking due to the potential presence of Giardia and other contaminants. Always carry enough water or a reliable purification method.

Given the trail's difficulty and high-altitude environment, you should pack layers of clothing, rain gear, plenty of water (and purification), snacks, a first-aid kit, sun protection, and sturdy hiking boots. Due to the lack of cell service after leaving Silverton, a downloaded map and compass or GPS device are essential for navigation.

At higher elevations, particularly in the rock gardens, you can often hear or spot pikas, small, rabbit-like mammals. The diverse terrain also supports various bird species and other small alpine creatures. Always observe wildlife from a distance and do not feed them.
