Ventės Ragas (literally 'world's edge') is a sparsely inhabited area on the tip of the south-pointing promontory of the delta, which, with its dramatic nature and uplifting isolation, is beautifully wild. Bar a few fishers' houses and the lighthouse (1862), the main attraction here is the Ventės Ragas Ornithological Station, 66km south of Klaipėda at the end of the Kintai-Ventė road.

A Teutonic Order castle was built here in the 1360s to protect shipping in the area, only for the castle and its church to collapse within a couple of hundred years due to the severity of storms on this isolated point (in German, it was called Windenburg meaning Windy Castle). The church was rebuilt, only to be storm-wrecked again in 1702. Its stones were used to build a new church at Kintai, 10km north on the regional park's northeastern boundary.
