Great Sand Dunes National Park, Colorado
Home to the tallest sand dunes in North America, Great Sand Dunes National Park features dunes that reach up to 750 feet (229 meters) high. These dunes sit at the edge of the San Luis Valley, framed by the Sangre de Cristo Mountains, creating a stunning contrast of sand and alpine scenery.

Imperial Sand Dunes, California
Also known as the Algodones Dunes, this dune system stretches over 40 miles along the southeastern California border near Arizona and Mexico. The dunes can reach heights of around 300 feet and cover roughly 45,000 acres, making it the largest mass of sand dunes in the United States. Popular with off-highway vehicle (OHV) enthusiasts, the area is a playground for dune buggy rides and sandboarding, but it also has fragile ecosystems, so certain areas are protected.

The coastal location offers a unique mix of sand dunes and ocean views, making it a popular destination for recreation and wildlife observation.
Coral Pink Sand Dunes, Utah
These dunes are distinctive for their striking pinkish hue, caused by the iron oxide in the Navajo sandstone that surrounds the area. The dunes cover approximately 3,000 acres and reach heights of up to 100 feet. Located near Kanab, Utah, this state park offers hiking, sandboarding, and photography opportunities in a more intimate and colorful dune environment compared to larger desert dune fields.
Monahans Sandhills, Texas
Spanning about 3,840 acres in West Texas, the Monahans Sandhills are famous for their soft, fine sand and rolling dunes that can reach heights of 70 feet.

The dunes are part of a larger desert ecosystem, featuring unique flora and fauna adapted to the sandy environment.
Kelso Dunes, California
Located within Mojave National Preserve, the Kelso Dunes rise approximately 650 feet above the surrounding desert floor, making them one of the tallest dune fields in the Mojave Desert.

The dunes offer challenging hikes and stunning desert vistas.
St. Anthony Sand Dunes, Idaho

Jockey’s Ridge, North Carolina
Jockey’s Ridge State Park features the tallest natural sand dune system on the East Coast, with dunes rising up to 100 feet in height. Located in the Outer Banks, these dunes are unique for their coastal setting and shifting sand formations influenced by ocean winds and tides.

Little Sahara Sand Dunes, Utah
This dune field covers roughly 60,000 acres in central Utah and features dunes that can reach heights of about 700 feet. The Little Sahara Recreation Area is a major destination for off-road vehicles, with miles of trails winding through the sand. The dunes are part of a larger desert basin and offer diverse terrain, including rocky outcrops and sand flats, appealing to both thrill-seekers and nature lovers.
How to Choose
When selecting which sand dunes to visit, consider what kind of experience you want. For sheer height and dramatic alpine backdrops, Great Sand Dunes National Park is unbeatable. If you’re interested in off-road vehicle riding, Imperial Sand Dunes and Little Sahara offer expansive terrain and amenities for OHVs. Coastal dunes like Oceano and Jockey’s Ridge provide a blend of sand and ocean activities with milder climates. Accessibility and level of development matter too: some dunes are within established parks with visitor centers and trails, while others are remote and require more planning. Finally, consider the ecosystem and season—some dunes can be extremely hot in summer or windy in certain months, affecting your visit.
