Visiting a national park this summer?
Be prepared to pay more for the experience. Many national parks across the country, faced with tight budgets and delayed maintenance, are increasing entrance fees.
The National Park Service says 106 of the 128 parks that charge entry fees are raising those fees or planning to do so in the coming year.
The list includes many of the most popular parks such as Yellowstone, Yosemite and the Grand Canyon, as well as monuments and historic sites.
