Once the favoured destination of the Rana prime ministers from Kathmandu and their distinguished visitors, Chitwan is Nepal's most famous national park. Home of the elusive Bengal Tiger, visitors can observe rare one-horned rhinos, marsh crocodiles, bisons and elephants - close up. The Royal Chitwan National Park offers a mix of forests, marshlands, elephant grass up to 6 feet high, the river Rapti and the Lamital lake. The sunsets at Chitwan are a 'must see' and an ideal prelude to Tharu dancing and songs in the evening. Settlement and cultivation are strictly controlled with many buildings constructed of timber and thatched in elephant grass.
