Big Hill Lake Conservation Area offers extensive outdoor recreation opportunities around a 4,000-acre reservoir with diverse habitats supporting fishing, hiking, camping, and wildlife viewing.
Big Hill Lake Conservation Area lies along the Neosho River near the Kansas-Oklahoma border, encompassing over 4,000 acres of forested hills, rugged terrain, and the reservoir itself. The lake was created by the U.S. Army Corps of Engineers with the goal of flood control, water supply, and recreation. This conservation area is characterized by oak-hickory forests, patches of prairie, and abundant wildlife habitats including deer, turkey, and waterfowl. Visitors can enjoy a wide range of outdoor activities: the lake supports excellent bass, crappie, and catfish fishing, while the surrounding lands feature mountain biking and hiking trails that weave through diverse landscapes. Several campgrounds provide both primitive and developed camping options, many overlooking the lake. The area’s scenic bluff lines and water access points are popular for kayaking and canoeing. The region’s natural beauty is complemented by its quiet atmosphere, making it ideal for bird watching, photography, and family outings. Established decades ago as part of regional conservation efforts, it continues to attract visitors for those seeking varied terrain and water-centered outdoor fun. Its proximity to local towns makes it accessible while providing a sense of retreat into nature's tranquility. The combination of water and rolling hills supports a rich ecosystem, offering excellent opportunities to spot wildlife, especially during dawn and dusk. Overall, Big Hill Lake Conservation Area is valued both for its natural resources and recreational versatility in eastern Kansas and northeastern Oklahoma.
