The parabolic sand dunes reach heights between 20 to 60 m. Hinterland erosion and traditional coastal dune development have created this sand dune ecosystem. The dunes are thousands of years old and the park serves as an archeological place as well with various discoveries. Along with human remains, there have been finds of pottery shards and stone tools.
The dunes are comprised of a fine greyish brown colored sediment that differs from the traditional fine sandy tan dunes in most places. Additionally, the dunes have vines and shrubs covering much of them.
The Sigatoka Sand Dunes were the first national park declared for the country of Fiji and often described as one of Fiji’s natural wonders.
The national park encompasses an area of 1.77 sq km making it one of the smallest national parks in the world.
