If you can’t escape to the high elevation of the Rockies for your late summer camping trip, situate yourself in the heart of the Black Hills, instead. Custer State Park is larger than most national parks, and offers scenic drives, American bison viewing, multiple lakes, and challenging hiking. You’re at a high enough elevation to beat the heat, but also close to the historic towns of Deadwood and Keystone, not to mention that little monument called Mt. Rushmore.
Bonus: A hike up Custer State Park’s Black Elk Peak (formerly Harney Peak) takes you to even higher elevation, where the views stretch beyond the state.
Quick Tip: When car camping in the summer, freeze gallon jugs of water ahead of time, and use them as ice packs in your cooler. As they melt, you have ice water for drinking at your disposal, and you don’t have to find a place to discard thawed ice packs.
