Mammoth Access
About
Mammoth Access is a boat launch in Missouri, about 5.4 miles from the town of Briarwood Estates. For comfortable weather, fall is a good bet. Typical averages from the nearby Festus weather station show October highs around 70°F with lows in the mid-40s. May brings similar warmth, with highs in the mid-70s, though it averages more wet days. Mammoth Cave Overhang, a climbing area, sits just 0.1 mile away. Washington State Park offers more climbing about 2 miles off, and the 1000 Steps Trail and Rockywood Trail start about 2.5 miles away. Mineral Fork, a canoeing destination, is about 5 miles from the launch.
