Sullivan Lake State Park Adventures

Sullivan Lake State Park is located in the northern panhandle of Idaho, near the town of Naples within Boundary County. The park encompasses over 300 acres surrounding Sullivan Lake, a 580-acre natural lake characterized by clear waters and forested shorelines. The area is dominated by mixed coniferous forests, including cedar, fir, and pine species, providing habitat for wildlife such as deer, black bear, osprey, and various waterfowl. The park's terrain includes gentle slopes and waterfront access, making it suitable for both recreational use and relaxation. Established in 1965, Sullivan Lake State Park was created to preserve the lake’s natural beauty and offer outdoor experiences to visitors, including swimming, fishing, and boating. The lake supports rainbow trout and kokanee salmon, attracting anglers year-round. Hiking trails run through the forest, providing peaceful walks with opportunities to observe local flora and fauna. The park also features developed campgrounds and day-use areas, including boat launches and picnic facilities. One of the key landmarks is the Sullivan Lake Lodge area, offering amenities and access to lake-focused activities. Its remote northern Idaho location offers a quiet alternative to more crowded state parks, appealing to families, kayakers, and outdoor enthusiasts looking for a less commercialized lake experience. The park’s proximity to the Kaniksu National Forest further enhances its appeal as a gateway for extended wilderness exploration or mountain biking. Visitors come here for a blend of lakeside recreation and forested tranquility that is representative of Idaho’s rugged northern landscape.
