Entrance fees at national parks across the country, including Crater Lake, will be waived Saturday and Sunday.
The fee-free weekend, the third and last this summer, is meant to encourage Americans seeking affordable vacations to visit the national parks, officials said. Entrance fees will be waived at the 147 sites across the country that charge for admission. The 244 other parks, such as Oregon Caves National Monument, do not charge entrance fees.
In Oregon, fees will be waived also for Lewis & Clark National Historical Park.
In Northern California, fees will be waived at Lassen Volcanic National Park, Lava Beds National Monument and Whiskeytown National Recreation Area.
In Washington, fees will be waived for Mount Rainier and Olympic national parks, Fort Vancouver National Historic Site and Whitman Mission National Historic Site.
