Pintu Kota Beach is known for the natural rock arch that frames the sea on Ambon's southern coast. The beach itself is small and rougher than a resort strand, but the stone gateway gives it a strong visual identity and makes it a popular local outing.
Come for the coastline and photographs rather than a long swim. The site is best worked into a loop around Ambon's southern beaches and viewpoints, where the island feels greener and more open than the busy city around the bay.
