Park Information

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.

Fifty years ago, if you had arrived at the natural tunnel in Bennett Spring State Park, you would have seen a lake. Around 1964, a dam created from gravel and silt and reinforced with rebar and concrete blocked the upstream entrance of the natural tunnel. There is no record of how long the resulting lake lasted, but historical accounts state the dam failed after heavy rains, leaving only the portion of the structure seen today at the end of the trail. Walk the Natural Tunnel Trail today and imagine what it would have been like 50 years ago.
