Snow Lake is a stunning alpine lake nestled high in the Cascade Range, within the Alpine Lakes Wilderness of King County, Washington. Situated at an elevation of 1505 metres, this pristine body of water is a jewel of the Mount Baker-Snoqualmie National Forest, renowned for its clear, often turquoise waters and dramatic surroundings. It is formed by Upper Snow Lake and Lower Snow Lake, both contributing to its expansive beauty.
Visitors are consistently captivated by the breathtaking alpine scenery that unfolds around Snow Lake. The lake is framed by towering granite peaks, including the prominent Chair Peak and Guye Peak, offering panoramic views that are truly unforgettable. The serene atmosphere, coupled with the vibrant colors of the water and the surrounding wilderness, creates a deeply rewarding experience for all who venture here.
Before embarking on your journey, it's helpful to know that the Snow Lake Trail is a popular moderate to challenging hike, typically covering 6-7 miles round trip with a significant elevation gain. The trail is well-maintained and accessible from the Alpental Ski Area, making it a convenient wilderness escape from Seattle. While the path is generally clear, preparing for varied terrain and weather conditions is always wise, especially as the lake can remain partially snow-covered into early summer. Backcountry camping requires permits, so plan ahead if you intend to stay overnight.
The best time to visit Snow Lake is typically from late spring through early autumn, when the snow has largely melted, revealing vibrant wildflowers and huckleberry bushes. Activities abound, from invigorating swims in the chilly, crystal-clear waters to fishing for stocked rainbow trout. Many hikers enjoy a refreshing break by the lake, finding shady spots nestled among the pine trees to relax or even pitch a small tent.
The journey to Snow Lake itself is an experience, with the popular Snow Lake Trail offering stunning vistas and occasional waterfalls along the way. Once at the lake, the views extend to Roosevelt Peak and Chair Peak, providing ample opportunities for photography and quiet contemplation. The area's rich biodiversity means you might spot various wildflowers like red columbines and Indian paintbrush during the warmer months.
For those eager to explore further, the Snow Lake hiking routes connect to other incredible alpine destinations, including Gem Lake and Wildcat Lakes, offering options for longer backpacking trips.

The Snow Lake Trail is generally well-maintained. However, due to its alpine location, it can remain partially snow-covered into early summer (June/July) and snow can return in late autumn (October/November). Hikers should be prepared for varied terrain, including rocky sections and potential snowfields, especially outside of peak summer months. Always check recent trail reports before heading out.
Yes, the Snow Lake Trail serves as a gateway to other incredible alpine destinations. From Snow Lake, hikers can continue on to Gem Lake and Wildcat Lakes, offering options for longer day hikes or multi-day backpacking trips. These extensions provide opportunities to explore more of the Alpine Lakes Wilderness.
The main Snow Lake Trail is typically 6-7 miles round trip with an elevation gain of approximately 1,600-1,800 feet. It is considered a moderate to challenging hike. The terrain includes a mix of forested paths, rocky sections, and switchbacks, leading to a significant climb to the lake basin.
Beyond the stunning lake itself, hikers will encounter beautiful alpine scenery, including views of towering granite peaks like Chair Peak and Guye Peak. The trail also features occasional waterfalls, especially in spring, and during warmer months, you can spot diverse wildflowers such as red columbines, Indian paintbrush, and alpine mertensia.
The primary parking area for the Snow Lake Trail is located at the Alpental Ski Area. Parking fills up very quickly, especially on weekends and during peak season (summer and early fall). Arriving before mid-morning is strongly recommended to secure a spot, as it is one of the most visited lakes in the Alpine Lakes Wilderness.
A permit is not required for a day hike to Snow Lake. However, if you plan to stay overnight and engage in backcountry camping, a wilderness permit is required. These permits are typically obtained through a lottery system or on a first-come, first-served basis, so plan ahead if you intend to camp.
Direct public transportation to the Snow Lake trailhead at Alpental Ski Area is generally not available. Visitors typically rely on personal vehicles or ride-sharing services to access the trailhead, which is approximately 50 miles east of Seattle.
Winter hiking to Snow Lake is possible but significantly more challenging and requires specialized gear and experience. The trail will be covered in snow and ice, and avalanche danger can be present. Conditions can be harsh, with cold temperatures and strong winds. It's recommended only for experienced winter hikers with proper equipment like snowshoes, microspikes, and avalanche safety gear.
While the Snow Lake Trail is popular, its moderate to challenging difficulty and significant elevation gain might be strenuous for very young children or those unaccustomed to hiking. Families with older children or those with hiking experience may find it rewarding. Always assess your family's fitness level before attempting the full trail.
Yes, dogs are generally allowed on the Snow Lake Trail. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all visitors. Please remember to pack out all pet waste.
The Snow Lake area is home to diverse wildlife. Hikers might spot various bird species, small mammals like marmots and pikas, and occasionally larger animals such as deer or mountain goats. Fishing for stocked rainbow trout is also a popular activity in the lake.
Snow Lake is located within the Alpine Lakes Wilderness, so there are no direct cafes, pubs, or accommodation facilities right at the trailhead. However, services can be found in nearby towns along Snoqualmie Pass, such as North Bend or Cle Elum, which offer various dining and lodging options.
