Major Lake Park is a quiet lakeside spot in Hill City, perfect for a picnic, a wildlife break, or a quick detour off the Mickelson Trail. Look out for geese, deer, and the local osprey.

The Crazy Horse Memorial is one of the most iconic landmarks in the Black Hills. Still under construction, it’s set to be the world’s largest mountain carving and honors the Lakota leader Crazy Horse. Even in its unfinished state, it’s an impressive sight and carries a powerful story about Native history and resistance. You can see the sculpture from the road, but the visitor center offers a closer view, along with exhibits on Native American culture and the carving process.

As you head further south towards Custer, it feels like you're far from civilization. Buckthorn Mountain comes into view, surrounded by wide stretches of open greenery.

Custer is in the heart of the Black Hills. On this commune, you will find a few kilometers to the north - by taking the Crazy Horse Memorial Highway - "The Thunderhead Mountain" where the monument to the memory of Crazy Horse is located. In response to the gigantic statues of the 4 faces of the American presidents: George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln on Mount Rushmore, an Austrian-born sculptor wanted to pay tribute to the famous Lakota warrior Tashunka Witko - Crazy Horse. 985077174705 He sculpts an entire mountain trying to represent the historical figure riding his horse. It has been more than 30 years that only the head has been carved. Suffice to say that this work will certainly never be finished. The site, by its gigantism is impressive. It is an incongruous visit to make.
