10 Hidden Lakes In Northern California Locals Don’t Want Tourists To Find

Northern California hides some of the most breathtaking lakes you’ll ever see, tucked away from tourist crowds and Instagram hotspots. I’ve spent years exploring these pristine waters, guided by whispered directions from locals who reluctantly shared their secret swimming holes. While places like Lake Tahoe get all the glory, these hidden gems offer tranquility and natural beauty that feels almost magical. Ready to discover what Northern California residents have been keeping to themselves!

1. Boulder Lake (Trinity Alps Wilderness)

Boulder Lake rests in California’s Trinity Alps Wilderness amid granite outcrops and conifer forests. The commonly used Boulder Lakes Trail begins near Trinity Center and spans roughly 3.5 to 4.5 miles round-trip with about 800 feet of elevation gain, making it accessible for many hikers.

The path traverses lush meadows and leads through rocky ridges before arriving at the tranquil lake. At around 6,000 feet elevation, the lake lies in a high mountain basin with clear waters suitable for wading, photography, and picnicking. Several informal campsites are found near a neighboring smaller lake.

The trail is typically snow-free from late spring through early fall. Visitors enjoy solitude on weekdays, and Leave No Trace ethics help preserve its natural charm.

2. Toad Lake (Shasta–Trinity National Forest)

Toad Lake is nestled to the west of Mount Shasta within the Shasta–Trinity National Forest at approximately 6,950 feet in elevation. A rugged forest road leads most of the way, requiring a higher-clearance vehicle; from the trailhead, a well -marked path extends about 1.6 miles to the lake, gaining modest elevation.

The lake lies in a serene high alpine basin framed by meadows and rocky slopes and is known for brook, rainbow, and brown trout fishing. Surrounding the shoreline, delicate and rare plant species thrive.

The trail guides hikers along the water’s edge to a junction with the Pacific Crest Trail, which continues toward other lakes and peaks. Best hiked from late spring through early fall, the area remains peaceful and invigorating for nature lovers.

3. Emerald Lake (Trinity Alps Wilderness)

Emerald Lake lies deep within the remote Trinity Alps Wilderness, situated in a granite basin approximately 5,500 feet above sea level. Accessing the lake involves a combination of trail navigation and off-trail route-finding, often via the Stuart Fork Trailhead followed by less-defined routes.

The lake exhibits a vivid green hue influenced by glacial sediment and surrounding geology. Surrounded by high granite walls and dense forest, the area is remote and receives few visitors, offering solitude seldom found elsewhere in the region. No designated campsites or services exist nearby.

Hiking here is best suited for experienced backcountry travelers familiar with navigation and prepared for alpine conditions, including snow lingering into early summer. The reward is a serene, pristine alpine setting.

4. Independence Lake (Sierra County)

Independence Lake is an alpine reservoir north of Truckee, known for supporting the threatened Lahontan cutthroat trout. Managed for both conservation and recreation, motorized boats are restricted to reduce disturbance to the native trout population.

The lake’s high elevation ensures cold, clear waters year-round. Visitors access the lake by a maintained dirt access road, which may become inaccessible when wet. Scenic trails and small beaches make it popular for hiking, paddleboarding, and birdwatching.

The surrounding forest habitat attracts bald eagles, osprey, and deer. Although guides note visitor access, the lake remains relatively uncrowded due to limited amenities and active conservation measures. Summer months offer the best access conditions and wildlife observations.

5. Lake of the Woods (Shasta–Trinity National Forest)

Lake of the Woods lies in a remote region of the Shasta–Trinity National Forest west of Mount Lassen, nestled among cedar and fir forests at approximately 5,500 feet. The lake is reached via unpaved forest roads, which are often closed or muddy in spring and early summer.

The quiet lakeshore features old-growth trees and a primitive campground suitable for basic camping with minimal infrastructure. Wildlife such as beavers, frogs, and various birds inhabit the area, making it a peaceful spot for nature watching. Shoreline access permits swimming and simple paddling.

Though little promoted, the lake’s secluded character and natural surroundings make it a rewarding destination for those seeking solitude and a rustic outdoor experience.

6. Serene Lakes (Near Donner Summit)

Serene Lakes refers to twin alpine lakes – Lake Dulzura and Lake Serena – located near Donner Summit in Placer County. Situated just off Interstate 80 at around 6,800 feet elevation, the lakes are easily accessible yet feel secluded.

In winter, both freeze solid enough for ice skating during cold periods; in summer, the water warms sufficiently for swimming and paddling by mid-season. The shoreline includes a mix of private cabins and limited public access points, making access nuanced.

Surrounding conifers afford a scenic setting, and dark skies offer excellent stargazing opportunities. Cellular coverage is spotty, further enhancing the feeling of escapism. The area remains relatively quiet despite proximity to the highway, especially outside peak summer weekends.

7. Red Lake (Alpine County)

Red Lake lies at roughly 7,800 feet along Highway 88 near Carson Pass in Alpine County. Renowned for its reflective waters and surrounding aspen groves, it is easily accessed via vehicle parking areas just off the highway.

Anglers visit for opportunities to catch rainbow and brook trout, though the lake is relatively small. Autumn brings golden foliage from the surrounding aspens, enhancing its photo-worthy charm. The lake’s high elevation results in long snow cover into late spring.

While speculation exists about nearby springs, there is no verified documentation of natural hot springs at the lake. Camping at the lakeshore is not officially permitted; winter snow typically restricts access until early summer.

8. Woods Lake (Eldorado National Forest)

Woods Lake sits at about 8,200 feet elevation in Eldorado National Forest, near Carson Pass in Alpine County. Crossing off Highway 88, it is accessed by a short spur road. In summer, the lake is renowned for vibrant wildflower blooms in July, including lupine, paintbrush, and columbine.

A primitive campground of approximately 25 sites provides opportunities for short-term camping. Trails link to nearby destinations like Round Top and Winnemucca Lake. The lake’s clear, cold water is popular for paddling and brief swimming.

Due to high elevation, the access route generally opens from late June through early October. The alpine basin and relatively low light pollution make it a favorable location for stargazing.

9. Bucks Lake (Plumas National Forest)

Bucks Lake is a sizeable reservoir at approximately 5,200 feet in elevation within Plumas National Forest near Quincy. With over 17 miles of shoreline, it offers diverse recreational opportunities including boating, kayaking, fishing, and swimming.

The lake’s numerous coves and granite outcrops provide scenic spots for exploration and solitude. Wildlife sightings of osprey, bald eagles, and deer are frequent. Campgrounds and cabin rentals are available along the shore. Wildflowers bloom in spring and early summer along the water’s edge.

While occasionally mentioned by locals for quiet weekends, Bucks Lake remains less crowded than many Sierra lakes, preserving a peaceful atmosphere despite its infrastructure and size.

10. Lake Siskiyou (Mount Shasta Area)

Lake Siskiyou is a reservoir located just southwest of Mount Shasta City, created in 1968 by damming the Sacramento River’s headwaters. The lake offers a variety of recreational opportunities including swimming, fishing, kayaking, and paddleboarding. A scenic seven-mile loop trail encircles the lake, giving views of Mount Shasta from several vantage points.

The western shoreline provides more secluded picnic and swim spots compared to the more developed beaches. Anglers can catch brown trout and bass year-round, and periodic stocking supplements the fish population.

Nearby hot springs exist in the general Mount Shasta region, but none are located directly at the lake. Mornings in fall often feature a layer of fog, lending a mystical atmosphere to the landscape.
