WASHINGTON – People can find good deals in the national parks this summer despite tight budgets, rising fees and a huge backlog of maintenance work. Throughout most of the National Park System, visitors do not have to pay any entrance fees. Only 21 of the 147 with fees raised rates this year, by an average $1 per person and $5 per car. The system includes 390 parks, monuments, battlefields, recreation areas, historic sites and other areas. For those who want to avoid lines and crowds, 26 of the 58 national parks had fewer than a half-million visitors last year. By comparison, the 10 busiest each attracted between 2 million and 9 million visitors.

Especially since it is free at the vast majority of parks,” parks spokeswoman Elaine Sevy said. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
