Named for the infamous George Armstrong Custer and the Battle of Little Big Horn, Custer State Park has 17,000 acres of natural beauty and adventure. There are several ways to explore the dozens of miles of trail in the park but hiking and biking are the most popular. If your feet are tired you can go on the Buffalo Safari Jeep Tour, the Hayride and Chuck Wagon Cookout, take a guided tour on horseback, or rent a kayak or canoe to explore the park by water.

It’s also home to the 7,242-foot Black Elk Peak (formerly called Harney Peak) where you can see four different states from the summit. Black Elk has a unique ecosystem of rocky slopes and classic cragged peaks where you can spot mountain goats, bighorn sheep, and elk or you can toss your line in the water for the aquatic wildlife.

Mount Rushmore National Memorial

The Mount Rushmore National Memorial is the crown-jewel of an Iron Mountain Road trip. Located in Keystone, Mount Rushmore was completed in 1941 and has hosted millions of visitors since. It took sculptor Gutzon Borglum and his aptly-named son Lincoln around 14 years to carve the 60-foot heads of Presidents George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln.

You can spend hours walking around the main plaza and gazing up at the likenesses of the presidents but there’s more to do than sit and stare. The best place to start is Lincoln Borglum Visitor Center (which is temporarily closed through the rest of 2019) to see exhibits and watch a 14-minute movie that discusses the planning and execution of the monument.

After the Center you can stroll down Presidential Trail for a quick snapshot of the area. If you have a half to full day you should book yourself into a ranger-guided tour. If you’re more comfortable with your own pace you can also try an audio tour with facts about the area and carving Rushmore.

Worth Pondering…

Keep close to Nature’s heart…and break clear away, once in awhile, and climb a mountain or spend a week in the woods. Wash your spirit clean.
