Actually if you really really want to enjoy and take it the sight on a gorgeous day, the entire morning would be fine. 2 hours is only climbing up and down and taking enjoying the view - this excludes the journey back and forth. When we climb other wild great walls, we stayed up there for 3-4 hours. It took us about 6 hours in total from Beijing into the outskirts. However, if you just want to tell your friends you've been to the Great Wall (but not really enjoying it), I suppose two hours is enough - but that would be a real pity....of course if you join a tour, they just herdled you along...so I never join any group tours...
