The island of Penang is also a federal state on the west coast of the peninsula. It is Malaysia's most famous destination, and hardly needs an introduction. Georgetown is known not only as a city full of history, but also for the long beach at Batu Feringghi with its lovely hotels and the expansive view of the sea. The island is connected to the mainland by the Penang Bridge, measuring 13.5 km in length, making it one of the longest bridges in Asia. Sights include: Fort Cornwallis, which today is home to an outdoor museum and acts as an open-air theatre, Penang Bird Park, the Orchid and Hibiscus Garden, the leisure park at Bukit Mertajam and the small but extremely interesting butterfly farm just North of Batu Feringghi.
