3) Yellowstone National Park, Wyoming
Yellowstone is a fantastic budget option for outdoor enthusiasts. While there are park lodges, hotels and sit-down restaurants, those who looking to save on accommodations can set up camp in one of the 12 available campgrounds. There you can cook your own food and enjoy the surrounding nature and abundant wildlife. Many campsites are equipped with showers, toilets and laundry facilities. Summer is the most popular time to visit, and the most expensive. The ideal time is Spring or Fall with fewer people and a bit cooler temperatures. While there is an entrance fee, once you are in the park, the pass is good for a week for both Yellowstone and Grand Teton National Park. A car is needed to get around the different regions of the park and can be rented at any of the surrounding airports. Once you choose an area, you can settle in and explore the many wonders.
