In the heart of desert slot canyon territory in southwestern Utah is my favorite place on the planet: Zion National Park. While Zion is fairly small compared to other national parks, it has an abundance of hiking opportunities through much diverse terrain. From arid desert sections to breathtakingly majestic viewpoints to lush forests and claustrophobic slot canyons, there is a lot of beauty that most casual visitors never see.
