Camp right off the Beartooth Highway (near Yellowstone). This area offers many amazing photo opportunities, beautiful scenery, and a chance to cool off in the river during the warmer months.
Coming out of Cooke City, MT follow the Beartooth Highway (named the most scenic byway in the U.S.) toward Beartooth Pass. Go about 8 miles.
Once you drop back down into Wyoming and pass the Fox Creek campground on your left, start looking for the small break in the trees on your left. There is a clearing and turn in on your right as well. You may pass it the first time, I always do!
Once you find it, turn in and you'll see the Clarks Fork of the Yellowstone right in front of you! There's a fantastic campsite and pull in right there on your right. Great fishing, swimming, and camping await! If you walk down the trail a little, you'll get to see a beautiful cascade waterfall.
Beware, it is a VERY heavy Grizzly bear area. I you are tent camping, I recommend not staying here alone. Or at least carrying bear protection.
This is probably my favorite car camping site ever!
NOTE: There is no cell service here. If you need to make a call or get internet, drive further up the pass just past the first major overlook on the left (after the seasonal forest service compound), you should get 3-4 bars and 4G at the pullout on the right.
