Technically this is the Changxing Island ferry terminal, but for the ferry over to Hengsha Island. Ferry runs approx. every 20 or 30 minutes, cost for the return ticket is RMB 20 per person and bike (as of Aug 2023). As the ferry is the only access to Hengsha Island, you only need to buy the ticket for the outgoing route and it is checked only once. The return is already included.
