The beautiful Niobrara River attracts thousands of visitors every year. Designated as a National Scenic River by Congress in 1991, it’s also part of the National Parks family. The river winds through deep canyons with high cliffs, around pine-topped hills, and past many waterfalls. Trips down the river can be made by canoe, tube, kayak, and even stock tank! And your journey can last anywhere from a few hours to a few days.
