This circular trail features a unique landscape of parallel rampart-type sand dunes and grassy swamps among the dunes. The 3.5 km trail leads through a landscape that is unique in Europe and emerged some 6,000 years ago as the sea was receding. This landscape offers evidence of the geological history of the Baltic Sea. There is a high-type swamp (the Pēterzers swamp), along with remnants of an old narrow-gauge railway. Wooden pathways have been installed along the swamp and the surrounding wetlands.
