Round Lake State Park

Round Lake State Park centers on a small, clear glacial lake in the forested hills of northern Idaho, about 10 miles south of Sandpoint. The lake itself is the reason people come here. Formed by glacial activity thousands of years ago, it sits in a quiet bowl of second-growth forest with remarkably clean water and a calm, unhurried atmosphere that sets it apart from busier recreational lakes in the region. It draws swimmers, paddlers, campers, and families looking for a low-key outdoor experience without a long drive into the backcountry.

Swimming and Paddling on Round Lake

The lake is the park’s main draw, and the swimming beach is where most visitors spend their time. The water is cool and clear, with a gradual sandy entry that works well for children. A designated swim area keeps the beach safe and comfortable during peak summer weekends. Gasoline motors are not permitted on Round Lake; electric motor boats and non-motorized watercraft such as kayaks, canoes, and stand-up paddleboards are allowed. The calm water and compact size of the lake (roughly 58 acres) mean even beginners can paddle the full perimeter without difficulty. Fishing from the shore or a non-motorized craft is also popular, with the lake supporting perch and other warmwater species.

Forest Trails Around the Lake

A trail loops the entire perimeter of the lake and passes through mixed forest of western red cedar, Douglas fir, and birch. The loop is under two miles and stays close to the water for much of its length, offering frequent views across the surface. The terrain is gentle, making it accessible to most visitors including those with young children. A longer trail extends into the surrounding forest for those who want more distance and elevation. These trails are also used for cross-country skiing and snowshoeing in winter, when the park stays open and takes on a completely different character. The snow cover in this part of northern Idaho tends to be reliable through January and February.

Camping at Round Lake

The park has a campground with over 50 sites, including 16 serviced sites with water and electricity are available, along with standard campsites. Sites are spread through the trees close to the lake, and several walk-in tent sites offer more separation from neighbors. The campground fills on summer weekends, particularly in July and August, so advance reservations are strongly recommended during those months. Facilities include restrooms, drinking water, and fire rings at individual sites. The campground is also open during winter months for those interested in a cold-weather stay, though services are reduced.

Pet Policy

Pets are welcome at Round Lake State Park and must be kept on a leash no longer than six feet at all times. This applies on trails, in the campground, and throughout the park. Pets are not permitted in the swim area or on the designated swimming beach. Owners are required to clean up after their animals. Given the presence of wildlife in the area, keeping pets leashed also reduces the chance of an encounter with deer or other animals near the trails and campsites.

Wildlife to Be Aware Of

Black bears are present in the forested areas of the park. They are generally not aggressive toward people but are attracted to food, trash, and scented items left unsecured at campsites. Campers should store all food in a vehicle or bear box when not in use, dispose of garbage in the designated receptacles, and avoid leaving anything with a strong scent outside overnight. Do not approach a bear if you see one; give it space and make noise to let it move away on its own.

White-tailed deer are common and often visible near trails and campsite areas, especially in the early morning and evening. They may appear calm and accustomed to people, but feeding them is not permitted and creates problems for both the deer and other visitors. Keep a respectful distance and do not allow children or pets to approach them.

Osprey and various waterfowl nest along the shoreline during spring and early summer. These birds are sensitive to disturbance during nesting season. Paddlers and swimmers should avoid areas where birds appear to be nesting, and observers should keep a reasonable distance rather than approaching for a closer look. Watching from shore or from a stationary position on the water is the least disruptive approach.

Practical Information

Round Lake State Park is located at approximately 48.16694° N, 116.63667° W, about 10 miles south of Sandpoint in Bonner County. From Sandpoint, take US-95 south and follow signs for the park. The nearest town with full services is Sandpoint, which offers lodging, groceries, and dining.

The park is open year-round. Summer is the busiest season, with the swim beach and full campground services available from late spring through early fall. Winter visits are quieter and focused on skiing and snowshoeing.

Entry fees are $7 per vehicle for Idaho residents, with higher fees for non-residents. Camping fees are charged separately. The $10 Idaho State Parks Passport is available to Idahoans and covers day-use access to Idaho state parks; out-of-state guests can purchase an $80 annual Motor Vehicle Entry Fee sticker. Campsite reservations can be made through the Idaho Department of Parks and Recreation reservation system and are recommended well in advance for summer weekends.
