Lake of the Ozarks State Park

Lake of the Ozarks State Park is the largest state park in Missouri, encompassing 17,626 acres of rugged Ozark hills and forested ridges along the deeply indented shoreline of the Lake of the Ozarks — itself one of the largest man-made lakes in the United States, created by Bagnell Dam on the Osage River in 1931. The park stretches across a dramatic landscape of forested bluffs, coves, karst hollows and lake-shore terrain in the central Missouri Ozarks.

With more than 85 miles of Ozark trails, two public swimming beaches, boat launches, cave tours, equestrian trails and a marina, the park is a premier year-round outdoor destination in Missouri. It is also home to the Ozark Caverns, a show cave of unusual cave formations (including ‘angel showers’ — water weeping through cave formations), and the park’s karst terrain features sinkholes, springs and bluffs typical of the Ozark plateau. With its vast acreage, its spectacular lake setting, its cave, its trails and its rich Ozark forest, Lake of the Ozarks State Park is a beloved and comprehensive natural destination.

Summer is the busiest season, with the lake beaches, boating and swimming at peak demand — arrive early on weekends, as the beaches can be crowded. Spring brings wildflowers and mild weather ideal for hiking and exploring the cave, and fall brings spectacular color to the Ozark hills and the lake shoreline, a premier autumn time. Winter is quiet, with the trails and the cave open year-round.

The cave tours are available year-round (the cave maintains a constant temperature). Spring and fall offer the best hiking weather, and fall color over the lake and forested hills is outstanding. Check Missouri State Parks for beach hours, cave tour schedules and campground availability before visiting.

The vast forested acreage, the lake shoreline, the coves, the karst hollows and the caves of Lake of the Ozarks State Park host white-tailed deer, foxes, wild turkey, bald eagles (common over the lake in winter), great blue herons, ospreys and a rich community of woodland birds, while the lake supports largemouth bass, crappie, catfish and diverse fish species, and the cave shelters bats. The large, contiguous forest provides important habitat for Ozark wildlife across a broad landscape.

Bald eagles concentrate over the lake from late fall through early spring, and the coves and lake shore offer excellent birding for wading birds, waterfowl and raptors.

The lake is large and the water conditions can change rapidly — wear a life jacket when boating or kayaking, check weather forecasts before going on the water, and be aware of boat traffic on the busy main lake. Swim only at the designated beaches where lifeguards may be present; do not swim in undesignated areas or around boat launches. Cave tours involve uneven, sometimes wet footing; wear sturdy shoes.

The hiking trails can be steep and rocky in the Ozark hills; carry water and wear appropriate footwear. In the cave, follow the guide, never touch formations, and follow bat-protection rules. Supervise children near the water and on steep trails, and carry a map in the large park.

Lake of the Ozarks State Park offers a broad range of outdoor recreation on its 17,626 acres — hiking and backpacking on more than 85 miles of trails through the rugged Ozark hills and along the lake shore, horseback riding on dedicated equestrian trails, swimming at two public lake beaches, boating and fishing from the park’s boat launches and marina, cave tours of the Ozark Caverns, camping in multiple campgrounds, picnicking, mountain biking and wildlife watching.

Kayaking and canoeing the coves and inlets of the lake from the park’s shore offers peaceful paddling away from the busy main lake. The cave, the lake, the trails and the beaches together make the park a comprehensive and beloved all-season destination in central Missouri, drawing families, hikers, paddlers, equestrians and anglers alike.

The Lake of the Ozarks was created in 1931 when Bagnell Dam impounded the Osage River, one of the largest hydroelectric projects of its time, flooding the Ozark hill farms and communities to create a massive 54,000-acre reservoir. Lake of the Ozarks State Park was established to preserve a large tract of the surrounding Ozark forest and the lake shoreline for the public, protecting the forested hills and the karst terrain alongside the growing resort development of the broader lake area.

The park’s trails, campgrounds and cave have served generations of visitors since the 1930s, and the park continues to be Missouri’s largest and most comprehensive natural retreat on the famous Lake of the Ozarks.

Lake of the Ozarks State Park sits on the carbonate-rock Ozark plateau, where the soluble dolomite and limestone have been dissolved by water over immense time to create the karst terrain — sinkholes, springs, caves and hollows — that characterizes the park. The Ozark Caverns preserve the subterranean product of this dissolution, with formations including the ‘angel showers’ where water weeps through living formations.

The lake shoreline itself reflects the deeply dissected character of the Ozark hills, where the impounded Osage River and its tributaries created a highly irregular shoreline of coves, points and inlets in the forested Ozark terrain. The rugged bluffs, hollows and ridges of the park are classic Ozark karst topography.

Lake of the Ozarks State Park protects 17,626 acres of Ozark forest, karst terrain, lake shoreline and cave, a diverse and ecologically significant landscape where the large contiguous forest, the cave (with its bat populations), the lake coves and the karst features support a broad range of plant and animal life. The park’s size makes it one of the most important natural reserves in central Missouri.

Protecting the forest, the cave and its bats, the lake’s water quality, the karst features and the wildlife sustains both the ecological value and the recreational appeal of Missouri’s largest state park for future generations.

Lake of the Ozarks State Park, the largest state park in Missouri, holds an important place in the state’s outdoor-recreation heritage, preserving a vast natural retreat alongside the famously resort-heavy and development-intensive Lake of the Ozarks. While the broader lake is known for its resorts, marinas, water parks and entertainment, the state park provides the wild, forested counterpart — a place of trails, wildlife and natural karst beauty amid the vacation bustle.

The park embodies the balance between recreation and conservation on Missouri’s most iconic man-made lake, and has served generations of campers, hikers, paddlers and nature lovers as the natural heart of the Lake of the Ozarks region.

Lake of the Ozarks State Park is in central Missouri near Osage Beach and Kaiser, off State Route 134 from US-54, about three hours from St. Louis and Kansas City. The park is free to enter; cave tours and some facilities charge fees.

The park offers multiple campgrounds (electric and basic), hiking and equestrian trailheads, two public swimming beaches, boat launches and a marina, the Ozark Caverns show cave (scheduled guided tours), picnic areas and a visitor center. The park is large — bring a map and plan your areas before arriving. Check Missouri State Parks for cave tour schedules, beach hours, campground availability and conditions before visiting.

Missouri State Parks protects the vast Ozark forest, the lake shoreline, the cave and its bats, the karst features, the trails and the wildlife of Lake of the Ozarks State Park. Visitors help by protecting the lake’s water quality (no littering or pollutants in or near the water), following cave rules that protect bats (including from white-nose syndrome), staying on trails, packing out all trash, respecting wildlife, and following park rules.

As the largest state park in Missouri and a critical natural reserve on the intensively developed Lake of the Ozarks, protecting the park’s forest, cave, karst and wildlife is essential to preserving the region’s natural character.

The park is free to enter; cave tours require tickets and run on a schedule. The cave may be entered only on guided tours; never touch formations. Follow bat-protection and decontamination rules. Swim only at designated beaches. Boating requires Missouri registration and adherence to lake regulations. Camp only in designated campgrounds. Equestrian use is on designated trails. Fishing requires a Missouri license.

Pets must be leashed and are not allowed in the cave. Drones require authorization. Collecting is prohibited. Pack out all trash. Check Missouri State Parks for current rules, tour schedules, beach hours and conditions before visiting.

The resort town of Osage Beach (with its outlet mall, restaurants and entertainment), the broader Lake of the Ozarks resort area, Ha Ha Tonka State Park with its castle ruins, the Bridal Cave show cave, Camdenton and the Lake of the Ozarks region define the surroundings, with the cities of Jefferson City, Columbia, Springfield and Kansas City within a few hours.

Lake of the Ozarks State Park anchors the natural heart of the Lake of the Ozarks region, providing a vast forested and karst retreat amid the resort development, and is the essential nature destination for any Lake of the Ozarks visit.

With 17,626 acres and more than 85 miles of trails, plan ahead — get a trail map, pick your campground and reserve early, especially for summer weekends when beaches and campgrounds fill fast. Tour the Ozark Caverns for the unusual ‘angel showers’ cave formations; check the schedule and book ahead.

Kayak the quiet coves from the park’s launches to escape the busy main lake, hike the forested ridge trails for lake views, and visit in fall for spectacular Ozark color over the water. Watch for bald eagles over the lake in winter, and stay in the park rather than the resort strip for a quieter, nature-immersed Lake of the Ozarks experience.
