Pulau Penyenget, reachable by frequent boats (8000Rp) from Bintan’s main pier, was once the capital of the Riau rajahs. The ruins of the old palace of Rajah Ali and the tombs and graveyards of Rajah Jaafar and Rajah Ali are clearly signposted inland. The most impressive site is the sulphur-coloured mosque, with its many domes and minarets.
