The map below shows the major highways and roads that connect Zion National Park with other attractions in the surrounding areas: 1  Coming from Las Vegas: 2  Take Interstate 15 (I-15) north from Las Vegas for roughly 130 miles. 3  Just past the bustling town of St. George, Utah, get off at Exit 16 and follow Route 9 east.
1) Zion deserves more time than you've allotted, and there are more easy hikes there than the Grand Canyon. Basically at the Grand Canyon, most people look at viewpoints, walk along the rim and maybe go down Bright Angel a little ways. So many more hikes to do at Zion with a lot more variety. Since it is 2 hours closer to Vegas than the Grand Canyon, you may even be able to do/see something on Saturday evening when you arrive.
