Ha Ha Tonka State Park near Camdenton, Missouri is one of the most scenically distinctive parks in the Midwest, combining the ruins of an early-20th-century stone castle with dramatic Ozark karst topography including sinkholes, caves, underground streams, and natural bridges. The park's centerpiece is the Castle Ruins, the remains of a 60-room stone mansion begun around 1905 by Kansas City businessman Robert McClure Snyder, who died in one of Missouri's first automobile fatalities before the house was completed. His sons finished a portion of the structure, but it burned in 1942 and was never rebuilt. The roofless stone walls now stand on a bluff 250 feet above Lake of the Ozarks, framing panoramic views of the lake coves and forested ridges below. The Castle Ruins Trail from the main parking area is approximately 0.75 miles and climbs steeply to the ruins in about 20 minutes. The Spring Trail descends from the castle site to a large natural spring that issues from the base of the bluff and feeds directly into the lake — one of the most visually striking spring systems in Missouri. Additional trails explore Colosseum Sinkhole, a 70-foot-deep collapse feature, a natural bridge, and Turkey Pen Hollow, a quiet cove accessible on a longer 3-mile loop. The park has no food, water, or visitor center, so visitors should bring supplies. Free admission and stunning scenery make it one of the best value attractions in Missouri's Ozark region. Sunrise and golden-hour visits provide the most atmospheric light on the castle walls. Fall foliage from late October through early November is spectacular from the castle overlook.
