The Curonian Spit is a 98-kilometre ribbon of sand running between the Baltic Sea and the Curonian Lagoon, half in Lithuania and half in Russia. The Lithuanian side is a national park; the southern half belongs to Kaliningrad Oblast. It is one of the strangest landscapes in Europe — pine forests planted to stabilise the dunes, ribbon villages of wooden houses, fishing in the lagoon, and the occasional dune still drifting eastward.
A paved cycle path runs the length of the Lithuanian section and is the best way to see the spit. Driving is allowed but a vehicle fee applies and parking in Nida is tight in summer. The UNESCO listing dates from 2000 and protects both the natural dunes and the surviving traditional architecture.
