Frequently Asked Questions

How long does it typically take to jog this loop?

The Moraine Lake Loop is designed for jogging and typically takes around 1 hour and 40 minutes to complete. This duration can vary based on your pace and how often you stop to enjoy the scenery.

What is the terrain like on the Moraine Lake Loop?

This loop is rated as difficult, featuring a significant elevation gain of over 400 meters. The terrain will include varied surfaces suitable for jogging, but expect challenging sections due to the elevation and the wilderness setting. You'll traverse parts of several official trails, including the Three Sisters Loop Trail and the Moraine Lake Trail #17.1.

Are dogs allowed on the Moraine Lake Loop?

Yes, dogs are generally allowed on trails within the Three Sisters Wilderness. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all visitors. Always pack out any waste.

What is the best time of year to jog the Moraine Lake Loop?

The best time to jog this loop is typically from late spring through early fall (June to October), when the snow has melted, and the trails are clear. Always check current trail conditions and weather forecasts before heading out, as conditions can change rapidly in the mountains.

Do I need a permit or pay an entrance fee to access the Three Sisters Wilderness?

Yes, the Moraine Lake Loop is located within the Three Sisters Wilderness, which often requires a wilderness permit for day use or overnight stays, especially during peak season. Additionally, a recreation pass (such as a Northwest Forest Pass or America the Beautiful Pass) may be required for parking at some trailheads. Check the U.S. Forest Service website for the most current permit and fee requirements before your visit.

Where does the Moraine Lake Loop start, and what are the parking options?

The loop begins and ends near the Devils Lake Campground & Trailhead. This is a popular starting point, so parking can fill up quickly, especially on weekends and during peak season. Arriving early is recommended to secure a spot.

What points of interest can I see along the route?

Along the Moraine Lake Loop, you'll encounter several notable features. You'll pass by Devils Lake, traverse the Three Sisters Wilderness boundary, and reach the Moraine Lake junction before arriving at Moraine Lake itself. These offer beautiful natural scenery and opportunities for short breaks.

Does this trail intersect with other well-known paths?

Is the Moraine Lake Loop suitable for beginner joggers?

Given its 'difficult' rating, 12 km distance, and over 400 meters of elevation gain, this loop is generally not recommended for beginner joggers. It requires a good level of fitness and experience with trail running. Beginners might find shorter, flatter trails in the area more suitable.

Are there any amenities or facilities near the trailhead?

The Devils Lake Campground & Trailhead offers basic facilities, including restrooms. However, services like cafes or extensive shops are not directly at the trailhead. It's best to come prepared with all necessary supplies, including water and snacks, as you are entering a wilderness area.

What should I bring for a jog on this trail?

For this difficult 12 km loop, essential items include sufficient water (there are no reliable water sources on the trail), appropriate trail running shoes, layers of clothing for changing weather, a map or GPS device (like komoot's app), snacks, sun protection, and a first-aid kit. Don't forget your wilderness permit if required.
