Must see · Canyon · Nature / Park
Grand Gulf State Park is a state-operated, privately owned and publicly accessible, geologic preserve near Thayer, Missouri, encompassing a forked canyon that is the remnant of an ancient collapsed dolomite cave system. The land that is now the park was acquired by conservationist Leo Drey (1917–2015) before becoming part of the Missouri state parks system. The 322-acre (130 ha) state park has been operated by the Missouri Department of Natural Resources under a lease agreement with the L-A-D Foundation since 1984. Grand Gulf was declared a National Natural Landmark in 1971 as an excellent example of karst topography and underground stream piracy. A 60-acre (24 ha) portion of the park was designated by the state as the Grand Gulf Natural Area in 1986.

  • Driving in the area and stopped to do a tranquil 15 minute hike in hardwood forest-nicely maintained dirt trail well marked representative of Missouri hill country. Parking sufficient for 12 cars and put toilet, picnic tables overlooking bluff.
  • The intermediate hike was definitely easy. I doubt anyone who hikes regularly would call this intermediate but it was fun all the same 😊
