Reyneke Island is a summer recreation location for the Primorsky Krai region, and tourism is an important part of the local economy. The island is popular due to its pebbly and sandy beaches, the deciduous forest (oak, acer and tilia) on the western part of the island, and the meadows on the eastern part. Pinales of the Korean pine variety are found on the island. The islet of Vykent Island and many kekurs are found around the coast.
