Farragut State Park's Buttonhook Bay is a quiet, secluded place at the southwest corner of Lake Pend Oreille. It's a short walk from nearby Beaver Bay Beach, a popular swimming and fishing spot.
Buttonhook Bay mostly serves as a dock for boats exploring Idlewilde Bay and the larger Lake Pend Oreille, but visitors can also swim from the docks. The water here is a bit cooler than at Beaver Bay Beach, which is either a plus or minus depending on how warm the day is. No lifeguard sits on duty here, so bring a personal flotation device if you plan to spend much time in the water. Pets and glass containers are not permitted here.
Farragut State Park is a large complex with seven campgrounds and trails that link various parts of the park. During the busy summer season youth groups make use of the park, but the facilities remain open to other visitors year round. It was once a World War II naval training facility, where submarines made use of the depths of Lake Pend Oreille. Farragut State Park was named after David Farragut, the first admiral of the U.S. Navy, who was appointed during the Civil War. It became a state park in 1965.
