Just five minutes from Yellowstone's west entrance at West Yellowstone, Montana (the most popular and convenient entry point), you'll find a pine-shaded site that is the perfect base camp for exploring the world's first national park. Old Faithful puts on its steamy regular-as-clockwork show just 30 miles east. Have a tour bus pick you up at KOA's office for a ride to the park. Or take the wheel yourself to tour Yellowstone's driving loops. The area offers horseback riding, world-class fly-fishing, whitewater rafting, a nightly Old West Rodeo and hiking/biking trails that begin at the KOA. Return for a soak in the indoor pool and hot tub housed in a classic Montana log building. Fuel up with a latte and pancakes every summer morning and barbecue each evening. Save room for delicious homemade fudge sold in the campground store! Pool: May 22 - September 18. Max pull thru: 90 feet. Your hosts: the Linde family.
