The trails is very wet and tussocky - difficult walking. 2-3 days should be allowed for any trip downstream from the airstrip to Braye Lakes, Horsfeld Creek, etc. Some of the ridges are steep shale and difficult to cross. During the spring, creek levels can be low in the morning and impassable by late afternoon. Heavy rainstorms can quickly raise the creek levels.
Avalanches can be a problem in some areas during the early spring.
Bears may be present in the area. Travel in this area should be done only by experienced parties in good physical condition. One should also be able to read and follow a map and compass. This is a remote area and the hiking is strenuous. Help is not readily available.
