The Angels Landing is the most spectacular and most popular hiking trail in Zion National Park. But before deciding if you want to do it or not you have to answer two questions:
Are you afraid of heights or not?
If you do it is probably better to stick to less demanding trails. The last stretch of the trail is pretty nerve racking when you climb along the narrow ridge with the one-mile abyss on the one side and half a mile void on another. It is beautiful but scary sometimes. My wife is afraid of heights and there is absolutely no way she could complete this hike.
