Just follow 13600-S west and turn off when the road starts to turn north. If you reach the Kennecott Mine Fee Station the you have gone too far. This road will take you to the mouth of Butterfield Canyon. Another route is to take Exit 99 off I-80 and take route 36 south for 10 miles to Tooele and Main Street. Turn left on Vine Street and it will turn into Middle Canyon Road. Keep heading east to reach the canyon. Butterfield entrance is blocked off during the winter. It usually opens back up in late May or early June. There is still an opening for ATVs and Snowmobiles though. If there is not enough snow on the road for snowmobiles this is a great place to let your dogs run leash free, but have your leash handy in case there are horseback riders around. The road is paved all the way to the pass and turns into a dirt road, but is still drivable by car. White Pine Loop trail is 3.5 miles RT, and is mainly a biking trail. It is a 1 mile climb to Butterfield Pass. From here you can continue east through Butterfield Canyon, or north that will climb 1.5 miles to the summit with an overlook view of Kennecott Copper Mine. The view of the pit is definitely worth the extra mile. Back at the pass head SW on a wide trail that will turn into a single path and will drop down into White Pine Canyon and turn right for .75 a mile downhill back to the trailhead.
Coral Pink Sand Dunes State Park
Turn south onto Redwood Road from Bangerter and drive 8.14 miles, and turn west onto SR 73 (Cedar Valley Road). Follow this road for 20.64 miles and there will be a sign to Five Mile Pass. Park anywhere and enjoy the ride. There are trails for miles and miles. If you keep heading north/east you will eventually end up hitting a bunch of roadblocks preventing you from entering into the old mining town of Mercur. The place is shut down to the public and there is no trespassing.
Head west on I-80 towards Wendover and take exit 41. Turn south over the freeway and follow the signs to the dunes. There is a daily usage fee, and flags are required.
From 7800-S head west until you reach HWY-111 or Bachus HWY and turn north. There will be an open dirt area on your right about a mile down the road. This open area has mounds of dirt and some race tracks mainly for Sports ATV's but is still fun for Utility ATV's and I've even seen a few Off-Road vehicles driving around.
Turn south onto Redwood Road from Bangerter, and drive 18.6 miles to reach the first dirt road turnoff to the west. You can continue driving south to various other turnoffs. This location is also a popular spot for target practice so be aware of ricocheting bullets if your near anyone shooting.
