Near Troy, the 6,393 acre Cuivre River State Park offers miles of trails, most of which are open to both hikers and equestrians. The trails are of varying length and difficulty and wind through forested hills, steep valleys, glades, prairies, and offer great views atop Frenchmans Bluff. All the trails in Cuivre River State Park open for public use are identified with entrance signs and marked at intersections with colored directional arrows. Occasional colored markers are used to identify trails where the route is not clear. At points where hiking and equestrian use separate, symbols indicating the appropriate direction of travel are used. Trail users are advised to watch closely for trail markers, especially where the trail intersects old roads. Two campgrounds are available, one for equestrians with electric and non-electric sites (13 total). The other campground has over 90 sites with both electric and non-electric sites.

Lone Spring Trail -- 6 miles
Lone Spring Trail consists of two three-mile loops, one north and one south of Highway KK. The trail is named for a perennially flowing spring that emerges in the valley at the base of a ridge. The northern portion of Lone Spring Trail, which is open to hikers and backpackers only, loops through Northwoods Wild Area and crosses Big Sugar Creek, a designated state natural area.

Blazing Star Trail -- 2 miles
The trail begins on the southern side of Sac Prairie, near where the Prairie Trail starts. After crossing through a wooded creek valley, the trail enters an open expanse of tallgrass prairie. It then alternates between wooded savanna and open prairie, until the loop returns you through the creek valley and back up to the parking lot. Note: A separate trail entrance connects the trail loop to the campground. Summer and fall are the best times to see many of the wildflowers, while the tall prairie grasses reach their peak during the fall. Occasionally, the trail may be closed for a prescribed burn to preserve the prairie, savanna and woodland ecosystems.
Overall, Cuivre River State Park is the 18th most popular horse trail of all 19 horseback rides in Missouri.
