The tallest dunes in North America are up to 750 feet tall and neighbor grasslands, shrublands and wetlands. They were formed by sand deposits of the Rio Grande on the San Luis Valley, and the park also has alpine lakes, six 13,000-foot mountains, and ancient forests.

Amazing views, exhausting hike. Consider switchbacks when going up steeper sections, along with plenty of water.
