The short version
Most people walk out to the castle, take a picture, and leave. That's a fine hour, but the better part of the park is down below the bluff.
If you have half a day, start at the castle, then drive to the lake parking lot and take the Spring Trail back to the spring. Wear real shoes. Everything below the bluff is stairs and rock, and every trail down to the water comes back up.
The castle ruins
Robert McClure Snyder, a Kansas City businessman, started building the castle in 1905, two years after he first saw the property. He died in a car accident in 1906, and his sons finished the house in the early 1920s.
The family used it as a summer home, and in the late 1930s it ran as a hotel. A fire gutted it in 1942. The state bought the castle and grounds in 1978 and opened them as a park.
The Castle Trail out to the ruins is paved and works for strollers and wheelchairs from either castle parking lot. It's the busiest trail in the park for a reason: the overlooks along it look straight down into the valley where the spring runs out to the lake.
The spring and the natural bridge
Ha Ha Tonka Spring is the 12th-largest spring in Missouri. It runs out of the base of the bluff through a short valley to the Niangua Arm of the lake, and the water is a different color than anything in the main channel.
The valley the spring runs through is an old cave system that fell in. What's left standing includes the natural bridge, a span of rock big enough to walk under, and it's the shadiest spot in the park on a hot afternoon.
Trails
There are about 15 miles of trail, and most of it comes in short pieces. These are the ones worth planning around. The full list is on the park's trail page.
| Trail | Length | Rated | Why go |
|---|---|---|---|
| Castle Trail | 0.4 mi | Easy | The ruins and the view over the lake. Paved. |
| Spring Trail | 1.4 mi | Moderate | Down to the spring and back up. |
| Colosseum Trail | 0.6 mi | Rugged | The natural bridge and the Colosseum. |
| Turkey Pen Hollow Trail | 6.5 mi | Rugged | The long loop, if you want the park to yourself. |
Hours and getting there
The park is at 1491 State Road D, Camdenton, about five miles south of town. From November through March the gates are open 8 a.m. to sunset. Hours change with the season, so check the park's hours page before an early start in summer.
The castle and the spring each have their own parking. The Spring Trail starts from the lake parking lot.
Pair it with
Bridal Cave is on the other side of Camdenton, so the two make an easy day. If you'd rather swim afterward, Lake of the Ozarks State Park has two public beaches. On a hot day, check today's lake level and water temperature before you go.
