From Highway 15 take Utah State Route 9 through hurricane Utah to Zion national Park. Once in the Park take Zion Canyon scenic drive toward the Lodge. This road follows the Virgin River up into the canyon. Keep your eyes open for safe places to turn out.
If you're planning to visit Zion national Park I would recommend getting a good map, and plan on exploring some of the less traveled trails. Zion certainly has some well-known hikes like Angels Landing and the Riverwalk that you must see. But I would also recommend getting away from the crowds you'll be surprised what you find on some of the less traveled trails.
This photograph of the Virgin River was taken in Zion National Park right after him a large winter storm had passed. I used a very mild HDR technique to blend the high contrast scene. I also used DXO to make some corrections for the fisheye distortion.
