Utah's nature-made subway ride is Bucket List worthy

While Zion National Park has no train, it does have a subway, and the lottery to visit this subway has just opened up for the year. This cylindrical slot canyon is so popular only 80 permits are issued per day, and a lottery reservation system is enacted between March and November to handle peak demand. Getting to this curvy canyon is no small task. The 9.5-mile round trip hike is strenuous and requires technical skill. But if popularity and beautiful images are anything to go by, the journey is well worth it. Take a ride on nature's subway below.
