“Embark on an epic trek through Idaho's Sawtooth wilderness, brimming with diverse landscapes and historical intrigue.”
Embarking on the Alice Lake, Twin Lake, Edith Lake Loop, hikers will traverse a challenging yet rewarding path that spans approximately 34 kilometers (about 21 miles) with an elevation gain of roughly 1100 meters (approximately 3600 feet). This loop, nestled in the scenic Sawtooth National Recreation Area near Blaine County, Idaho, is a test of endurance and offers a diverse array of landscapes.
Getting to the Trailhead To reach the trailhead, hikers can drive to the Sawtooth National Recreation Area, located near the town of Ketchum. From Ketchum, take Highway 75 north for about 40 kilometers (25 miles) until you reach the turnoff for the Sawtooth National Recreation Area. Follow the signs to the designated parking area for the Alice Lake trailhead. Public transport options are limited in this region, so driving is the most feasible option for accessing the start of the hike.
Navigating the Trail The loop begins at the Alice Lake trailhead, where hikers will immediately be greeted by the steady climb through dense forests and alpine meadows. The first segment of the trail leads to Alice Lake, a stunning alpine lake surrounded by towering peaks, which is reached after approximately 8 kilometers (5 miles) of hiking. Here, hikers can take a moment to enjoy the serene waters and the reflection of the jagged Sawtooth Mountains.
Continuing on, the trail ascends towards Twin Lakes, which lie nestled in a dramatic glacial basin. This section includes a steep climb, but the reward is a pair of pristine lakes, perfect for a mid-hike break. The trail then loops around, offering views of the White Cloud Mountains to the east.
Wildlife and Natural Features As hikers progress, they may encounter a variety of wildlife, including deer, elk, and possibly even black bears or mountain goats. It's essential to be bear-aware, carrying bear spray and knowing how to store food properly. The region is also home to a diverse array of flora, with wildflowers blooming in the meadows during the summer months.
Historical Significance The Sawtooth National Recreation Area is rich in history, with the Sawtooth Mountains being a central part of the Idaho mining boom in the late 1800s. While hiking, one may come across remnants of this era, including old mining equipment and abandoned cabins.
Final Ascent and Descent After Twin Lakes, the trail makes its way towards Edith Lake, which is often less crowded, providing a tranquil setting for those who make the journey. The final leg of the loop descends back towards the trailhead, with the total elevation gain distributed throughout the hike, making for a strenuous but manageable ascent.
Preparation and Planning Given the trail's difficulty, hikers should be well-prepared with adequate supplies, including water, food, and layers for changing weather conditions. It's also advisable to download the trail map onto a navigation tool like HiiKER to ensure proper route-finding throughout the hike.
Seasonal Considerations The best time to hike this loop is from July to September when the snow has melted, and the trail is most accessible. Outside of these months, hikers may encounter snow and ice, requiring additional equipment such as crampons and an ice axe.
This loop offers an immersive experience in the Idaho wilderness, with breathtaking views, challenging terrain, and the chance to explore the natural beauty of the Sawtooth National Recreation Area.

Activity types
The Alice Lake, Twin Lake, Edith Lake Loop is 34.4 km, or about 21.4 miles, with 1,199 meters of climbing, so it is typically done as a multi-day backpacking trip rather than a single-day hike. Strong hikers may cover it in a very long day, but most parties split it over 2 to 3 days to allow time at Alice Lake, Twin Lakes, and Edith Lake.
This loop is commonly accessed from the Tin Cup Hiker Trailhead at Pettit Lake in the Sawtooth National Recreation Area. The trailhead sits off Highway 75 via Pettit Lake Road, and parking is limited because it is one of the busiest access points for Alice Lake and the surrounding Sawtooth Wilderness.
The Alice Lake, Twin Lake, Edith Lake Loop is rated medium, but the numbers make it a serious outing: 34.4 km of hiking with 1,199 meters of elevation gain. The route is better suited to hikers comfortable with long mountain days, sustained climbing, and backpacking terrain in the Sawtooth backcountry.
Yes. The Alice Lake, Twin Lake, Edith Lake Loop is a multi-day route in the Sawtooth backcountry, and backpackers commonly camp near the lake basins along the loop. Large groups of 8 or more need a permit in this area, and standard Sawtooth Wilderness regulations apply, including checking current fire restrictions before an overnight trip.

The route links three named alpine lake areas: Alice Lake, Twin Lakes, and Edith Lake, all set in the Sawtooth National Recreation Area. Alice Lake is especially well known for big mountain views, and the broader Pettit Lake trail system also connects to other classic Sawtooth destinations such as Toxaway Lake and Farley Lake.
The best window is usually mid-summer into early fall, when high-country trails around Alice Lake and Twin Lakes are more likely to be snow-free. Early season can bring lingering snow above about 7,500 feet, high creek crossings, and downed trees, which can make this 34.4 km loop significantly more demanding.
