Moonlit Lake Camp

← Back to Trail Logs

Trail Overview

The Moonlit Lake Camp is a two-day, 18-kilometer camping trek that leads hikers to one of the most serene alpine lakes in the region, nestled at 1,800 meters above sea level in a glacial basin surrounded by jagged peaks. This trail offers the rare combination of moderate physical demand and extraordinary reward — the approach is challenging enough to feel like a genuine adventure, yet manageable enough for hikers with reasonable fitness and basic backpacking experience. The destination, a pristine alpine lake whose still surface reflects the sky like a mirror, is the kind of place that makes you forget about the weight on your back and the miles still ahead.

What elevates this trek above a typical alpine lake hike is the overnight experience. Camping beside the lake at altitude is a transformative experience that simply cannot be replicated on a day hike. As dusk settles over the basin, the surrounding peaks catch the last rays of sunlight in shades of pink and gold while the lake transitions from blue to deep indigo. And then the stars arrive — not the diminished, light-polluted sky that most of us are accustomed to, but the full, staggering spectacle of the Milky Way arcing overhead in a river of light so dense it casts faint shadows on the shoreline. On clear nights, the reflection of the stars on the lake surface creates the uncanny illusion that your tent is suspended in space, floating between two identical skies.

Fishing is another highlight that draws visitors to Moonlit Lake. The lake supports a healthy population of brook trout and rainbow trout that thrive in the cold, oxygen-rich waters, and early morning casts from the shoreline can be remarkably productive. A valid fishing license is required, and catch-and-release practices are strongly encouraged to preserve the fishery for future visitors. Whether you fish or not, the simple pleasure of sitting beside the water with a hot cup of coffee, watching the morning mist burn off the lake as the sun crests the ridge, is worth every kilometer of the approach.

Route Description

The trek begins at the Moonlit Lake trailhead, located at the end of a well-maintained gravel road that climbs through second-growth forest for 10 kilometers before reaching the parking area. Day one covers approximately 10 kilometers of trail that ascends steadily through a mixed forest of Engelmann spruce, subalpine fir, and lodgepole pine. The first 4 kilometers follow an old fire access road that has been converted to a hiking trail, offering a gradual warm-up with a gentle grade. At the 4-kilometer mark, the trail leaves the roadbed and transitions to a single-track path that begins to climb more aggressively through a series of switchbacks carved into the forested slope.

The middle section of day one is where the real elevation gain occurs. Over the next 4 kilometers, the trail climbs approximately 500 meters through subalpine forest, with the trees becoming progressively shorter and more widely spaced as you ascend. Several small streams cross the trail in this section, providing opportunities to refill water bottles if you are carrying a filter. The trail passes through a beautiful subalpine meadow at approximately 1,600 meters elevation, where late-summer wildflowers — including alpine aster, mountain heather, and Indian paintbrush — create patches of vivid color against the green meadow grass. The final 2 kilometers of day one traverse rocky alpine terrain before the trail crests a small ridge and the lake suddenly appears below, set in its granite basin like a sapphire in a setting of stone.

Day two is the return journey, covering the same 10 kilometers in reverse. The descent goes faster than the ascent, but the steep switchback section requires careful footing, particularly if the trail is wet or icy. A pre-dawn start is recommended for photographers who want to catch the first light on the lake, and the early morning hours are also the best time for fishing before the sun drives the trout to deeper water.

What to Expect

Scenery

The scenery on the Moonlit Lake Camp trek is extraordinary from start to finish, but it is the lake basin that leaves the deepest impression. The lake itself occupies a classic glacial cirque, with steep granite walls rising on three sides and a rocky outwash plain on the fourth where the lake drains via a small creek. The water is remarkably clear — you can see the bottom at depths of several meters, and the submerged rocks take on an otherworldly blue-green hue that shifts with the angle of the sun. The surrounding peaks retain their snow caps well into summer, and the contrast between the white snow, the grey granite, and the deep blue water is a photographer's dream.

At night, the scenery transforms entirely. Away from any significant light pollution, the night sky at 1,800 meters is among the darkest and most spectacular you will find outside of a designated dark sky preserve. The Milky Way is visible as a continuous band of light, and on moonless nights, the number of visible stars is staggering. Shooting stars are common, and the occasional satellite traces a slow arc across the heavens. The reflected stars on the still lake surface double the effect, creating a 360-degree celestial panorama that is, without exaggeration, one of the most memorable sights a camper can witness.

Trail Conditions

The trail is generally well-maintained and clearly marked, with rock cairns guiding the way through the alpine sections where the path is less defined. The lower forest section is smooth packed dirt with occasional roots, while the switchback section is rocky and can be muddy after rain. The alpine section above treeline is exposed rock and sparse vegetation, with no shade. Water is available from several streams in the lower and middle sections but should be treated before drinking. The lake water is clean but should also be filtered or treated as a precaution. Snow can persist on the upper portions of the trail into early July, and late-season hikers in October may encounter fresh snow at altitude. The designated campsites at the lake are equipped with rock fire rings and level tent pads, but there are no bear boxes or food storage facilities — carry a bear canister or hang your food.

Tips & Precautions

• Carry a bear canister for food storage. There are no bear boxes at the campsites, and hanging food is difficult in the alpine zone where trees are sparse or absent. Black bears are active throughout the area, and proper food storage is essential for both your safety and theirs.
• Pack warm layers for the overnight, even in summer. Temperatures at 1,800 meters can drop below freezing at night year-round, and the wind chill off the surrounding peaks can make it feel significantly colder. A warm sleeping bag rated to at least -5 degrees Celsius and a insulated pad are non-negotiable.
• Bring a water filter or treatment tablets. While the streams and lake appear pristine, all backcountry water should be treated to guard against giardia and other waterborne pathogens. A lightweight squeeze filter is the most convenient option for a two-day trek.
• Start day one early to allow ample time to reach the lake and set up camp before dark. The 10-kilometer approach with a full pack takes most hikers 5 to 6 hours, and the final alpine section is easier to navigate in daylight when the rock cairns are visible.
• Practice Leave No Trace principles rigorously. This is a fragile alpine environment with slow-growing vegetation that takes decades to recover from damage. Pack out all trash, use established campsites, and avoid building new fire rings or enlarging existing ones.
• Check the weather forecast before departure and be prepared to turn back if conditions deteriorate. The exposed alpine section is dangerous in lightning storms, and sudden temperature drops can occur without warning at altitude. Carry emergency shelter even on planned overnight trips.

Getting There

The Moonlit Lake trailhead is located approximately 2 hours from the nearest town. From the highway, turn onto Forest Road 17 and follow the gravel road for 10 kilometers to the trailhead parking area. The gravel road is suitable for passenger vehicles in dry conditions but can be rough and rutted after heavy rain. High clearance is recommended but not strictly required. The parking lot accommodates approximately 15 vehicles and includes a vault toilet and information board. A Northwest Forest Pass or equivalent is required for parking. A backcountry camping permit is not currently required for the Moonlit Lake campsites, but regulations may change — check with the local ranger district before your trip. The access road is typically snow-free from July through October.
