Frequently Asked Questions

What is the terrain like on the Highland Mary Lakes Trail?

The trail is primarily singletrack, featuring rugged and varied terrain. Expect steep ascents, rocky sections, and boulder fields that can be challenging to navigate. There are also creek crossings and marshy areas, especially near the lakes. The initial section is particularly steep, and as you gain elevation, you'll pass through forests and meadows before reaching rolling alpine tundra above the treeline.

How long does it typically take to complete the Highland Mary Lakes Trail?

While the komoot tour data suggests a shorter duration, given its 'difficult' rating and significant elevation gain, most hikers and advanced trail runners report a round trip taking 4-6 hours. This accounts for the challenging terrain, high altitude, and time to enjoy the scenic views.

Is the Highland Mary Lakes Trail suitable for beginner joggers?

No, the Highland Mary Lakes Trail is consistently rated as 'difficult' or 'hard' due to its steep ascents, rocky terrain, and high altitude (over 12,000 feet). It's more suitable for experienced hikers or advanced trail runners who are accustomed to challenging mountain environments and significant elevation gain.

What are the best times of year to visit the Highland Mary Lakes Trail?

The best time to visit is typically from late July through September. During these months, the snow has usually melted, and the alpine meadows are vibrant with blooming wildflowers. Always check local weather conditions before heading out, as high-altitude weather can change rapidly.

Are dogs allowed on the Highland Mary Lakes Trail?

Yes, dogs are generally allowed on the trail. However, as it is located within the Weminuche Wilderness, it's crucial to keep your dog on a leash to protect wildlife and ensure a pleasant experience for all trail users. Always pack out all pet waste.

Do I need a permit or is there an entrance fee for the Weminuche Wilderness?

There are generally no permits required for day hiking or entrance fees to access the Weminuche Wilderness for day use. However, if you plan an overnight backpacking trip, wilderness permits may be required. Always check the latest regulations with the USDA Forest Service or Colorado Parks & Wildlife for the most current information.

Where can I park to access the Highland Mary Lakes Trail?

The trail typically starts from the Cunningham Gulch Trailhead, which is located off County Road 2 near Silverton. Parking is available at the trailhead, but it can fill up quickly, especially on weekends during peak season. Arriving early is recommended.

What notable landmarks or viewpoints will I see along the route?

The trail offers spectacular high-altitude alpine vistas. You'll see impressive views of the Grenadier Range, including peaks like West Trinity, Vestal, and Arrow Peaks. The route follows Cunningham Creek, featuring numerous waterfalls, and leads to several crystalline alpine lakes, including the Highland Mary Lakes and Verde Lake. Don't miss the Highland Mary Lakes Overlook for breathtaking panoramic views.

What kind of wildlife might I encounter on the trail?

As the trail is in a high-alpine environment within the Weminuche Wilderness, you might spot various wildlife. Keep an eye out for marmots, pikas, and various bird species. While less common, deer, elk, and even bighorn sheep can occasionally be seen. Always maintain a safe distance and never feed wild animals.

Is the Highland Mary Lakes Trail a loop or an out-and-back route?

The Highland Mary Lakes Trail is primarily an out-and-back route. While it connects to other trails within the Weminuche Wilderness, the most common way to experience the Highland Mary Lakes is by returning along the same path.

What should I wear and bring for jogging on this trail?

Given the high altitude and challenging terrain, wear sturdy trail running shoes with good grip, and dress in layers to adapt to changing weather. Bring plenty of water, high-energy snacks, sun protection (hat, sunglasses, sunscreen), a map or GPS device, and a first-aid kit. Trekking poles can also be very helpful for stability on steep and rocky sections.
