Bring your own bed and a space in a campground is much cheaper than a room in one of the park’s lodges. Many campgrounds come equipped with showers, flushing toilets and even laundry facilities.
Skip the summer
Summer witnesses the largest influx of tourists, hotel and campground rates tend to rise. You’ll spend less if you visit during the off-season.
Do your own cooking
Yellowstone does feature several sit-down restaurants, but they can end up putting quite a dent in your savings. Consider bringing your own food.
Although there are several restaurants, cafeterias and snack shops within the borders of Yellowstone Park, consider bringing along a cooler with lunch items and snacks — so you don’t have to worry about staying near one of the park’s more developed areas.
