Feel free to add your comments and photos for Zion National Park here..... Without a doubt, my favorite National Park in the US is Zion, located in southern Utah. It's an easy 157 mile, 2.5 hour drive from Las Vegas where cheap flights and cheap car rentals abound. The town of Springdale, Utah can be your home base whether you're looking for a cute B&B, independent motel, or lower cost chain hotel. 2011 Entrance fees are $25 per car for a 7 day pass or $80 for an annual multi-park pass. National Park Service Website The best resource for Zion hikes and the surrounding area. It lists scores of hikes within the park in great detail and categorizes them by distance and difficulty. Zion can be a small, intimate park if you stay within the main canyon. If you're more daring, explore the back country trails located in the north west Kolob section of the park or the east side accessed by driving along route 9, also known as the Zion - Mt. Carmel Highway. As you enter the park from the south side(Springdale), the red, jagged, 200 million year old sandstone walls border you on each side with the Virgin River that carved the canyon flowing down the center. Deeper in the canyon, the walls will rise up 2000+ feet. Every season offers a unique experience in the park. From April 1st thru October 31st, Zion uses a shuttle bus system to preserve the sanctity of the park experience. The buses are fully accessible, quiet, and free. They start early in the morning and run throughout the evening starting in Springdale and continuing on to the 10-15 stops throughout the main canyon and back again. It's a great system that allows you to get on and off as you please and they run every 10-15 minutes throughout the day. Easy hikes include the Emerald Pools trail. Depending on the season, there will be 3 pools and 3 waterfalls. The 3rd pool actually has a small sandy beach that kids tend to enjoy.
