Zion National Park in Utah is divided into two sections. If you only have one day, plan to spend it in Zion Canyon. In only 8 hours, you can tackle four great hikes and soak up some of the most spectacular views the park has to offer.
When it comes to national parks, the U.S. is an embarrassment of riches. But Zion National Park in Utah is one of the best, likely because it literally feels like Mars. And who doesn't want to camp on Mars? The park has three campgrounds total, and it's best to go from March through November.
