Dune Climb to beach and back (MI)
The “Dune Climb” is the most famous feature of Sleeping Bear National Lakeshore (one of 4 Lakeshores in the NPS system), and is done tens of thousands of times every summer. It’s a stunning dune of pure white sand going right out of the parking lot. Most just do that, but if you keep going the angle eases up, you’re running through soft sand, until you top out, and suddenly, boom - the clear blue waters of Lake Michigan extend out past the horizon. It's beautiful and can be done barefoot.
