The Burwell area has plenty to offer aside from the Calamus Lake. Take a day to enjoy the wonderfully refurbished Civil War era Fort Hartsuff. Your whole family will love their time while taking in a lasting history lesson.
Take an educational jeep tour through the sandhills. These arrangements can be accomodated through the Calamus Outfitters.
Other options include a round of golf at the 9-hole Calamus Golf Course, a tubing adventure on the North Loup River (a bit more challenging than the Calamus), or a day trip to the chalk mines near North Loup, NE.
