Nagliai nature reserve protects the Dead dunes. Dead (Mirusios), or Gray (Pilkosios) dunes are large sandhills built by strong winds, with ravines and erosions.
Nagliai nature reserve is a place for habitats of rare plants, included in the Red Book, four villages and two old cemetery sites that are hiding under the sand.
Any human activity is prohibited in the reserve except for scientific observations.
In 1675–1854 four Nagliai villages here were covered in sand.
