BOAT
There are daily slow boats connecting Hon Gai district in Halong City with Hai Phong City . Boats depart Hon Gai at 6.30am, 11am and 4pm. It could be considered a cheap way to do a Ha Long Bay tour. There arc no longer hydrofoils linking Ha Long and Hai Phong, as travel by road is cheaper and just as fast. From Bai Chay, Mui Ngoc quarter (add: Halong Street) operates hydrofoils to Mong Cai leaving at Sam and 1pm; the ticket office is almost next door to the Mien Tay bus station. The trip is definitely preferable to the long road journey. Book ahead, as demand often outstrips supply. The best way to get to Cat Ba Island is to hop onto the regular tourist boats from Bai Chay tourist-boat dock.
BUS
-Buses from Ha Long City to Hanoi leave from Mien Tay bus station (Cai Lan Street) in Bai Chay every 15 minutes.
