Glacier Point is my favorite spot in Yosemite National Park. One reason is that it provides what I consider the best view of Half Dome. Another reason is that from the two sides of the point you can either view the valley floor to one side or spot the waterfalls from the other side. A lot of visitors don't make it up to Glacier Point because it is not obvious where it is located. The point is visible from the valley if you are near the Ahwahnee Hotel. Just look straight up. Just above 7,200 feet from where you are standing is the point. There are two ways to get to the point. The easy way is to take a 32-mile drive out of the valley going around the many granite formations, ending up in the parking lot. The hard way is to hike up the 4.6-mile trail (incorrectly named "Four Mile Trail) which ascends the 3,200 feet before reaching the point. I haven't hiked up the trail but I have hiked down it which wasn't easy. I can't imagine how challenging going up would be.
