Pine-topped bluffs frame the site of one of Nebraska's top state parks. Fort Robinson played a key role in America's frontier and military history during the wars with indigenous tribes and two World Wars, when the fort was used for cavalry training and housing of German POWs. A small marker shows visitors where the famous Sioux leader Crazy Horse was killed while in the Army's custody. Today's park serves as base camp for a wide range of family-friendly activities. A horse-drawn wagon tour provides an overview of the multi-layered history of the site and is a pleasant way to explore the expansive grounds. Two floors of the original post headquarters hold interpretive exhibits. Jeep and horseback tours head into the hills, and canoe/tube rentals take advantage of the fort's location along the White River. The Post Playhouse shows live musicals, while nightly rodeos give the youthful summer staff a chance to show off their riding and wrangling skills. Don't miss the Trailside Museum of natural history. Its star exhibit is a pair of mammoth skeletons, found with their tusks eternally locked in battle. An on-site restaurant serves dishes including a bison-filled take-off on Nebraska's signature Runza sandwich (something like the Eastern European equivalent of a calzone, only using ground meat).The old cavalry barracks have been converted into motel-style rooms, and officers' quarters now pull duty as rental cabins. Campers can choose from tent or RV sites. A Nebraska state park permit ($5 daily or $26 annual) is needed for each vehicle entering the park; visitors choose from a wide-ranging menu of daily activities, priced separately.
