It was an overcast cool day when we started out for the park yesterday. By late afternoon the sun came out but unfortunately a fierce wind also whipped up then, blowing sand into our faces. Despite the crazy, unpredictable weather we still had a great day and managed to hike quite a few trails. The park has 147,000 acres of sandstone canyons and high desert plateaus. Zion Canyon is the largest canyon in the park and the most accessible. A paved scenic drive follows the Virgin River along the canyon floor and through the park.
