Colchuck Lake is a hidden gem nestled in Washington’s Alpine Lakes Wilderness, and its pristine beauty makes it one of the most awe-inspiring lakes in the Pacific Northwest. With its deep, turquoise waters set against a backdrop of towering granite peaks, this lake offers a stunning visual experience that feels like something straight out of a nature magazine. Located near Leavenworth, it serves as a gateway to the famous Enchantments and draws hikers and adventurers from across the region.

The lake itself is renowned for its clarity and depth. Its glacial origins mean that the water is icy cold year-round, adding to its crystal-clear appearance. At about 5,570 feet in elevation, Colchuck Lake lies in a basin surrounded by iconic peaks like Dragontail Peak and Colchuck Peak. These towering granite walls reflect off the lake’s surface, creating a surreal, mirror-like effect. While swimming in the lake is an option for the brave, be prepared for bone-chilling temperatures even on the hottest summer days. The cold water, though refreshing, makes it more ideal for quick dips than extended swims.

For those who want to explore the lake further, non-motorized water activities such as paddling or floating on a raft or inflatable kayak are popular. However, because the lake sits in a protected wilderness area, you’ll need to bring your own lightweight inflatable if you plan to venture out onto the water. Fishing is another activity you can enjoy here, with cutthroat trout being a common catch. Just be sure to have a valid Washington state fishing license if you plan to cast a line.

To reach Colchuck Lake, you’ll need to embark on a moderately challenging hike. The trail to the lake begins at the Stuart Lake Trailhead, about 13 miles from the town of Leavenworth. From the trailhead, the hike is approximately 8 miles round trip with an elevation gain of around 2,300 feet. The first portion of the hike is relatively gentle as it meanders through dense forest and crosses small creeks. About halfway, the trail forks and you’ll take the left fork to head toward Colchuck Lake. As you approach the lake, the trail becomes steeper and more rugged, with rocky switchbacks leading to the final reward: the first glimpse of Colchuck’s brilliant blue waters through the trees.

The best time to visit Colchuck Lake is in late summer or early fall when the snow has melted and the trail is dry. However, even in the summer months, the weather can be unpredictable, with sudden temperature drops, especially in the morning and evening. Fall is particularly magical here as the larch trees turn golden, adding a pop of color to the already stunning landscape. Be sure to pack layers and plenty of water, as there are no facilities along the trail.

Given its location within the Alpine Lakes Wilderness, visitors should know regulations to preserve the area's natural beauty. A self-issue wilderness permit is required to hike here, and if you're planning an overnight trip, you'll need an overnight permit, which can be challenging to obtain due to the Enchantments’ popularity. As always, remembering to practice Leave No Trace principles is essential to maintain the pristine condition of the lake and surrounding trails.

Colchuck Lake may be one of the most breathtaking spots in Washington, but it remains a relatively less crowded alternative to the more famous spots in the Enchantments, like Lake Viviane or Snow Lakes. Its remote location and stunning hike offer a gorgeous experience for those willing to make the journey to the lake. Whether you’re just there for a day hike or using it as a basecamp for further exploration into the Enchantments, Colchuck Lake is a must-see for outdoor enthusiasts looking for a serene, jaw-dropping escape into nature.
