Idaho’s mountain ranges cradle some of America’s most pristine alpine lakes, offering peaceful retreats from busy everyday life. These hidden gems provide the perfect backdrop for fishing, kayaking, or simply enjoying nature’s tranquility.
Pack your camping gear and prepare to discover these seven serene mountain lakes where you can truly disconnect and recharge.
1. Redfish Lake: Sawtooth’s Sapphire Jewel
Nestled at the base of the jagged Sawtooth Mountains, Redfish Lake stretches five miles long with crystal-clear waters that mirror the surrounding peaks. The north shore bustles with activity, but countless quiet coves and secluded beaches await those willing to paddle along the shoreline or hike the perimeter trail.
Morning mist often blankets the water, creating a magical atmosphere as the sun rises. Visitors can rent kayaks or paddleboards to explore the lake’s hidden corners, or simply relax on the less-frequented pebble beaches away from the main lodge area.
Camping options range from developed sites at the Redfish Lake Campground to more secluded spots around the lake’s edges. The lake was named for the brilliant sockeye salmon that once turned its waters red during spawning season; a sight early settlers marveled at before dams reduced their numbers.
2. Payette Lake: McCall’s Forested Haven
Just steps from the charming mountain town of McCall sits Payette Lake, a 5,330-acre glacial gem surrounded by dense ponderosa pine forests. Unlike many mountain destinations, Payette offers both wilderness experiences and nearby amenities, making it ideal for those who want nature without complete isolation. T
he lake’s north shore remains relatively undeveloped, providing peaceful coves and beaches accessible by boat or the hiking trails that wind through Ponderosa State Park. Early mornings and weekdays offer remarkable solitude even during summer months.
Anglers appreciate the lake for its mackinaw and rainbow trout, while wildlife enthusiasts might spot deer, eagles, and occasionally moose along the shoreline. Fall brings spectacular colors as the surrounding aspens turn golden, creating a photographer’s paradise with fewer visitors than the peak summer season.
3. Alturas Lake: Sawtooth’s Secret Sanctuary
While most visitors flock to its famous neighbor Redfish Lake, Alturas Lake remains a tranquil alternative just 20 minutes south. This alpine lake sits at 7,000 feet elevation and spans about 750 acres of pristine mountain water with significantly fewer crowds even during peak season.
The eastern shoreline offers several primitive campgrounds tucked among lodgepole pines, where campers can fall asleep to the gentle lapping of waves. Fishing enthusiasts prize Alturas for its abundant kokanee salmon and rainbow trout populations that thrive in its cool depths.
A scenic 4-mile trail circles much of the lake, providing hikers with stunning vistas and access to secluded beaches. The shallow north end warms enough for comfortable swimming by mid-summer, creating perfect conditions for families seeking both adventure and relaxation without the noise and bustle of more popular destinations.
4. Priest Lake: Northern Idaho’s Wilderness Gem
Tucked against the Selkirk Mountains near the Canadian border, Priest Lake feels worlds away from civilization. The 19-mile-long lake maintains remarkable clarity, with visibility often exceeding 30 feet beneath its surface. Local residents call it “Idaho’s crown jewel” for good reason.
The eastern shore houses small communities and rental cabins, but the western shoreline remains largely undeveloped, protected within the Kaniksu National Forest. Visitors access secluded coves by boat, finding private beaches where footprints may be the day’s only human evidence. Island hopping creates perfect day adventures, with Bartoo Island offering hiking trails and peaceful picnic spots.
The lake’s northern section connects to Upper Priest Lake via a serene two-mile thoroughfare navigable by canoe or kayak; a journey that rewards paddlers with even greater solitude amid old-growth cedar forests and abundant wildlife including moose, osprey and even occasional woodland caribou.
5. Stanley Lake: Gateway to the White Clouds
Framed by the imposing profile of McGown Peak, Stanley Lake delivers postcard-worthy mountain reflections without the crowds. This compact alpine lake sits just 7 miles west of the tiny town of Stanley, yet feels remarkably remote once you settle along its shores.
The lake’s relatively small size (about 180 acres) means it warms more quickly than larger mountain waters, making summer swimming pleasant by Idaho standards. Stanley Lake Creek Campground provides simple accommodations with direct lake access, while dispersed camping options exist for those seeking greater privacy.
Sunrise photographers gather at the eastern shore viewpoint, where McGown Peak’s 10,000-foot summit catches the first golden light. Kayakers often spot osprey diving for fish, while hikers can access the stunning Alpine Way Trail system directly from the lake’s southern edge. Winter transforms the area into a peaceful snowshoeing destination with far fewer visitors than summer months.
6. Warm Lake: Boise National Forest’s Hidden Retreat
Despite its name, Warm Lake isn’t particularly warm; it’s the welcoming atmosphere that gives this mountain gem its character. Located 26 miles east of Cascade in central Idaho, this 640-acre lake sits at 5,300 feet elevation surrounded by dense forests and meadows bursting with wildflowers in summer.
The lake features several small, rustic resorts and campgrounds along its northern shore, while the southern half remains largely undeveloped. Families appreciate the gradual entry at North Shore Beach, perfect for children to splash safely while parents enjoy mountain views.
Kayaking reveals hidden coves where deer come to drink at dawn and dusk. Anglers cast for rainbow trout and kokanee salmon in waters that reach depths of 120 feet. Fall brings spectacular colors as tamarack trees turn golden against the evergreen backdrop, reflecting perfectly in the often-calm morning waters before the afternoon mountain breezes create gentle ripples across the surface.
7. Alice Lake: Sawtooth’s Backcountry Treasure
For those willing to work for their solitude, Alice Lake delivers wilderness perfection. This alpine jewel requires a moderate 5.5-mile hike through the Sawtooth Wilderness, ensuring only dedicated nature lovers make the journey.
Your reward? A pristine mountain lake nestled in a granite basin at 8,600 feet, where crowds never gather. The surrounding peaks, including El Capitan and Snowyside Peak, create a natural amphitheater that amplifies the sense of isolation and grandeur. Backcountry camping spots dot the shoreline, though permits are required and visitors must practice strict Leave No Trace principles.
The lake’s exceptionally clear waters host native cutthroat trout visible from shore. Wildflowers carpet the surrounding meadows from mid-July through August, creating vibrant displays of lupine, paintbrush and columbine. Snow typically blocks access until late June, but September offers magical experiences with fewer hikers, stable weather, and the beginning of fall colors painting the high-elevation landscape.
