The main purpose of this legislation is to ensure that visitors to national parks can pay entrance fees in cash. This is aimed at improving access to these recreational areas for everyone, regardless of their payment preferences or access to electronic payment methods. The key provision in this legislation mandates that all units of the National Park System that charge an entrance fee must accept cash payments. This requirement is intended to make it easier for people who may not have credit or debit cards, or who prefer to use cash, to enter and enjoy national parks.
