Walloon Lake, Michigan, spanning Charlevoix and Emmet Counties southwest of Petoskey, is one of Northern Michigan's premier inland lakes at approximately 4,320-4,584 acres with 30-31 miles of shoreline, an average depth around 28-30 feet, and a maximum depth of 100 feet—fed by springs for exceptional clarity and turquoise hues. Famous as Ernest Hemingway's childhood summer spot (with family cottage sites and a self-guided tour of related areas), it offers a rich literary and natural legacy. Activities include boating, swimming, fishing, kayaking, and watersports in summer, plus ice fishing and snow activities in winter, with nearby trails and the Village of Walloon Lake for charm. It empties into Lake Michigan via the Bear River, adding watershed appeal. Walloon Lake attracts families, retirees, vacationers, and history buffs with its serene beauty, clean waters, and resort-like feel. Real estate ranges from classic cottages to luxurious waterfront estates with private docks and panoramic views. Immerse yourself in the turquoise clarity and Hemingway-inspired magic of Walloon Lake.
