Garrison Dam Missouri River Breaks Loop
Missouri River breaks below America's biggest dam
This spectacular loop drops into the Missouri River breaks below Garrison Dam, where the massive spillway has carved dramatic canyons through ancient riverbed sediments. Starting at Riverdale, the route follows the old Corps of Engineers maintenance roads along Lake Sakakawea’s shoreline before plunging into the breaks themselves, where towering sandstone formations and hidden springs create an oasis in the high plains desert.
Moderate difficulty with some steep descents into the breaks and a few rocky creek crossings that can get interesting during spring runoff. High-clearance 4WD recommended, though experienced drivers can manage it in a capable SUV during dry conditions. The loop takes most of a day to complete properly, with plenty of spots to stop for photos or fishing. Summer gets hot down in the canyons, so spring and fall offer the best conditions. Pack water and snacks—no services once you drop below the dam.
