The cables allowing hikers access to the summit of Yosemite National Park's iconic Half Dome will be set in place this week.

Park officials say the metal cables on the mountain's steep granite shoulder will be up on Friday, weather permitting.

The 17-mile trail is strenuous with a 4,800 feet elevation gain, and is dangerous when wet. Officials say at least five people have died on the cables since 2006, nearly all with rain as a factor.

In recent years the route has been inundated with thousands of visitors a day, so last year park officials instituted a temporary 400-permit lottery for daily access. In the meantime, they are weighing different access options for the popular trail.

The lottery system ended in March, but about 50 permits per day are available through a two-days-in-advance lottery.
