This is straight from the US National Park Service website:
America’s Best Idea – the national parks – gets even better this summer with three fee-free weekends at more than 100 national parks that usually charge entrance fees*.
Mark your calendars for fee-free weekends this summer:
- June 20-21, 2009 (Father’s Day weekend)
- July 18-19, 2009
- August 15-16, 2009
And to make the fun even more affordable, many national park concessioners are joining the National Park Service in welcoming visitors on this summer’s fee free weekends with the their own special offers.
Here’s a tip – many national parks never charge an entrance fee, so you can plan inexpensive visits year round!
