Bai Tho Mountain - Attractive destination in Ha Long Only over 100m high, Bai Tho Mountain has a special terrain, on one side are busy small streets hugging the foot of the mountain, on the other side is surrounded by sea water, where boats come and gather. From the top of the mountain, you can see a whole corner of Ha Long Bay and the panorama from Hon Gai to Bai Chay. At dawn, the scene becomes even more magnificent with the morning mist rolling around the undulating rocky islands... and when dusk falls, the streets light up brightly.
