Grand Gulf State Park

Leashed pets are allowed at Grand Gulf State Park, a pet-friendly park in Thayer, MO. The park is one of the natural wonders of the Ozarks, presenting the most spectacular collapsed cave system in the area. 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 signs detail the formation of the gulf. Dogs are not allowed in any buildings, or public swimming areas and beaches. Visit Website
