Pesta Benak Sri Aman in Sri Aman
Pesta Benak, the Tidal Bore Festival, gathers the town of Sri Aman on Sarawak's Batang Lupar River to watch and ride the benak, a tidal wave that can rise roughly three metres as the incoming spring tide is funnelled upstream. About 200 kilometres from Kuching, the festival pairs this natural spectacle with boat races, kayaking, cultural pageants, concerts and riverside night markets.
Sri Aman sits on a bend of the Batang Lupar River in Sarawak, where a funnel-shaped river mouth produces one of the most reliable tidal bores in Southeast Asia.
