Alpine Lake

The primary trail to Alpine Lake, often starting from the Redfish Lake area, is generally considered intermediate. Hikers should expect challenging terrain, including significant elevation gain and rocky sections. Sturdy hiking boots are essential, and the route requires a good level of fitness. The total distance from the Redfish Lake Creek trailhead to Alpine Lake is approximately 5 miles (8.0 km) one way, not including the approach across or around Redfish Lake.

Parking is available at the Redfish Lake Creek trailhead, which serves as a common starting point for the hike to Alpine Lake. However, parking areas, especially around Redfish Lake, can fill up very quickly, particularly during peak season (late summer to early autumn) and on weekends. Arriving early in the morning is highly recommended to secure a spot.

Yes, Alpine Lake is located within the Sawtooth Wilderness, and a wilderness permit is required for entry. These permits are typically self-issued and free, available at trailheads, including the Redfish Lake Creek trailhead. It's crucial to fill out the permit completely and carry it with you throughout your hike.

The hike to Alpine Lake is generally considered challenging due to its length and elevation gain, making it less suitable for very young children or absolute beginner hikers. However, families with older, experienced children who are accustomed to longer hikes may find it rewarding. For beginners, it's advisable to consider shorter, less strenuous trails around the Redfish Lake area first.

Yes, dogs are generally allowed on trails within the Sawtooth Wilderness, including the route to Alpine Lake. 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.

Visiting Alpine Lake in winter is possible but presents significant challenges. The lake can remain frozen into early summer, and heavy snowpack can make trails impassable or require specialized equipment like snowshoes or skis. Accessibility to trailheads may also be limited by snow. Winter conditions are severe, and only experienced winter hikers or mountaineers should attempt this journey, being prepared for extreme cold, avalanche risk, and navigation difficulties.

Alpine Lake is in a remote wilderness area, so there are no direct amenities, cafes, or pubs at the lake itself. The closest services and accommodation can be found around Redfish Lake, which offers lodges, campgrounds, and a general store, or in the nearby town of Stanley, approximately 11.4 miles (18.3 km) northeast of Redfish Lake. It's essential to bring all necessary supplies for your hike.

Wild swimming is generally permitted in Alpine Lake, but visitors should be aware that the water is extremely cold, even in summer, due to its high elevation (8,337 feet / 2,541 meters) and glacial origins. The lake can remain frozen into early summer. Swimmers should exercise caution, be aware of hypothermia risks, and avoid swimming alone. There are no lifeguards or designated swimming areas.

The pristine Sawtooth Wilderness is home to a variety of wildlife. Hikers may have the opportunity to spot deer, elk, mountain goats, and various bird species. While less common, black bears and cougars also inhabit the area. Always practice Leave No Trace principles, store food properly, and maintain a safe distance from all wildlife.

Alpine Lake itself is a major scenic highlight, with its clear waters reflecting the dramatic surrounding peaks. Notable peaks include Packrat Peak (10,240 feet / 3,120 meters) at the southwestern end of the lake, as well as Old Monte Verita, Monte Verita Ridge, and Mount Alpen. The entire basin offers breathtaking panoramic views, especially from higher points along the trails that encircle the lake.

Alpine Lake is one of several stunning alpine lakes in the Sawtooth Wilderness. It is often distinguished by its particularly high elevation and the rugged, dramatic peaks that directly surround it, including Packrat Peak. While other popular lakes like Sawtooth Lake are also renowned for their beauty, Alpine Lake offers a similarly remote and pristine experience, often requiring a significant hike to reach, contributing to its serene atmosphere.
