The most noticable company doing rock climbing & deep water soloing in Halong Bay is Asia Outdoors. Asia Outdoors came to life in 2006 as Slo Pony Adventures. The company was formed by Erik Ferjentsik and Onslo Carrington, two adventure-minded American-certified climbing guides with backgrounds in private guiding and climbing gym operation in the US.
The courses offered range from basic to hard level, whether the client is a kid or a senior citizen, it doesn’t really matter. Price for each course is around 200 USD/person but will be reduced if the number of participants increase. Equipment for rock-climbing will be provided by Asia Outdoors and if you want to hire some more items, you can also find them at the shop of Asia Outdoors on the second floor of the Noble House Restaurant and Bar in Cat Ba Town. The place is also where you purchase entrance pass for each climbing spot before practicing the activities.
