3 Best Sights in Great Sand Dunes National Park, Colorado

Get a panoramic view of all the surrounding dunes from the top of High Dune. Since there's no formal path, the smartest approach is to zigzag up the dune ridgelines traversing about 2½ miles round-trip. High Dune is 693 feet high, and to get there and back takes about two hours, or longer if there's been no rain for some time and the sand is soft. If you add on the walk to the 741-foot Star Dune, plan on another two or three hours and a strenuous workout up and down the dunes.

Great Sand Dunes National Park's only picnic area is shaded by cottonwood trees with easy access to the sand and seasonal creek. It has a dozen places where visitors can park a car or small RV near a picnic table and a grill.

If it's a hot day, take a drive to the falls section of the Zapata Falls Recreation Area, about 7 miles south of Great Sand Dunes National Park (and about 10 miles north of Alamosa). From the trailhead, it's a ½-mile hike to the 40-foot waterfall and a mildly steep trail, which can include wading in a stream and walking through a narrow gorge to view the falls (depending on water levels). Air temperatures in the gorge are always cool and inviting, and the falls are beautiful, but be careful of the current (and slippery rocks) here. A picnic area and restrooms are at the entrance. The trailhead is 3½ miles off Highway 150, between mile markers 10 and 11.
