"Some people call Grand Gulf State Park the “Little Grand Canyon.” Some just call it “breathtaking.” The park is one of the natural wonders of the Ozarks, presenting the most spectacular collapsed cave system in the Ozarks. The "Grand Gulf" stretches for more than a mile between 130 foot high walls. Visitors can view the gulf from trails on top or from the floor where they can walk under the natural bridge, which spans 250 feet with a 75-foot high opening. There is no official trail leading to the bottom so visitors should use extreme caution when attempting to access the bottom. Interpretive trails detail the formation of the gulf." ~ Missouri Department of Natural Resources
