Rinca, also known as Rincah and Rindja, is a small island near Komodo island, East Nusa Tenggara, Indonesia, within the West Manggarai Regency. It is part of Komodo National Park. The island is famous for komodo dragons, giant lizards that can measure up to 3 metres (9.8 ft) long. Rinca is also populated with many other species such as wild pigs, buffalos and many birds.
Being less known and less visited than Komodo, it is a good place to see the komodo dragon in its natural environment with fewer people to disturb them. Day trips can be arranged from Labuan Bajo on Flores by small boat at the park headquarters.
The island's area is 198 square kilometres.
Living conditions for local people on the island are often difficult. Education facilities, for example, are quite limited for children. Some non-government organisations help with the provision of books for children on Rinca. Local people must also take some care to avoid komodo dragons because komodos in the area occasionally attack and kill humans.
