Zion National Park is one of my favourite national parks in the US. I love seeing all those geologic formations. It is also one of the most visited national parks. I've visited the park twice. In 2013 I spent three days hiking in the Zion Canyon. I also hiked The Narrows, which is one the best day hikes I've done. I would like to one day also visit the Kolob Canyons section of Zion National Park, which is in a different corner of the park and which receives far less visitors.
