Updated: 10/20/2008 - It's an easy day-trip you'll really dig -- The Crystal Mine in Dog Valley, California draws kids and adults alike. If you live in Reno, the mine is only about a 38 mile drive. Just head north on US 395, get off at Bordertown, and turn left going over the highway, then turn right. Follow Long Valley Road along some railroad tracks. You'll come to a fork in the road, but keep going straight. Take in the scenery along the way, which includes desert and forest settings.
