User: What are the different types of fees that are charged in the US National Park?
Assistant: Experiencing a US National park to it's fullest may require different kinds of fees and charges. The entree fee to the park, can vary based on vehicle and visitor type, and also can be different across parks. If one has plans of visiting multiple national parks/preserves within 12 months, the national park pass can be a good purchase. Many national parks offer activities within the facilities with an extra fee. Some of the parks are equipped with restaurants and lodges for a proper meal or stay, and the fees are charged accordingly. Most of the parks, if not all would have convenience store in / attached / near to the visitor center, which can offer frozen meals and other merchandizes for a cost.
