Top of Half Dome, Yosemite, California. My son made it to the top of Half Dome, this is my edit of his photo taken with my camera. Good job son, proud of you.
The Half Dome Cable Route hike runs from the valley floor to the top of the dome in 8.2 mi (13 km) (via the Mist Trail), with 4,800 ft (1,460 m) of elevation gain. The length and difficulty of the trail used to keep it less crowded than other park trails, but in recent years the trail traffic has grown to as many as 800 people a day.
The final 400 ft (120 m) ascent is steeply up the rock between two steel cables used as handholds.
