Cucumber Creek RV Park is southeast Oklahoma's best-kept secret. Nestled in the Heart of the Kiamichi Mountains near Smithville, Oklahoma, on US Hwy 259, we have the perfect getaway for you, your family, or a group of friends. You can bring your own RV or rent one of ours, sit in the quietness of the wind blowing through the trees, or plop a lawn chair next to the creek and listen to the water gently flowing by. Whatever your relaxing needs are, we offer them at Cucumber Creek RV Park.
