Camp in the desert, ride down sand dunes, gaze at a starry sky or hike through marshes while visiting the Bruneau Sand Dunes. Located in a 4700-acre state park, it’s a must-see destination in southern Idaho, only about an hour from Boise and 25-minutes from Mountain Home.
The park is best known for housing the tallest single-structured sand dune in North America, with an elevation of 470 feet. Visitors can climb these dunes on foot or on horse-back, and thrill-seekers can sand board down the dunes.
The park is also home to campgrounds, hiking trails and an observatory, perfect for stargazing. Lots of wildlife roams the area, so don’t forget the binoculars! However you’re looking to experience the park, here’s everything you need to know about the Bruneau Sand Dunes.
The Bruneau Sand Dunes are NOT man-made
The Bruneau Sand Dunes are a natural phenomenon, formed over 14,000 years ago as a result of the Bonneville Flood. The flood left a U-shaped basin in the Idaho desert, where sand and sediment began to accumulate. Strong winds from the northwest and the southeast continued to carry sand from the surrounding steppes and deposited them in the middle of the basin, forming the dunes we see today.
These strong winds also help hold the dunes in place. Unlike most sand dunes, which shift frequently, the Bruneau Dunes remain relatively stable. Although there are many smaller sand dunes, there are two large sand dunes that dwarf the rest of the landscape.

When to Visit Bruneau Dunes State Park
Although the park is stunning all year-round, the best time to visit is in the fall, between September and November. Temperatures are slightly cooler this time of year, meaning visitors can take longer hikes and spend more time traversing the dunes.
The park takes on a whole new character in the winter, when visitors can go sledding down the dunes. Just be aware that the park can get very cold this time of year. Alternatively, the summer can be scorching hot, so if you are visiting that time of year, be sure to visit the park early before the midday heat.
