Here’s a way to save while enjoying your summer vacation: The 145 national parks and historic sites that normally charge entrance fees will not be doing so on August 14 and 15, according to the National Park Service.

The National Park Service runs 392 parks and historic sites in 49 states. The ones that typically charge, such as Wyoming’s Yellowstone National Park, home of Old Faithful, cost between $3 -$25 per person.

The fee-free days are being held, according to the organization’s website, “to make it easier to experience America's Great Outdoors.” You can check out this website to find a park near you.

Additionally, the National Park Services will be offering free admission on September 25, which is National Public Land’s Day and November 11, which is Veteran’s Day.

All fee waivers include entrance fees for individuals, automobiles and/or commercial tour fees. Other fees such as reservation, camping, tours, concession and fees collected by third parties are not included. However, many concessioners will be offering their own special discounts on each fee-free day.

For example, Delaware North Companies Parks and Resorts, who services all of Delaware’s National parks, are offering $5 coupons good for shopping, dining, recreational activities and tours. Swan Mountain Outfitters, which sells outdoor gear and services in Montana’s Glacier National Park, will be offering $5 horseback riding coupons to families, groups and Montana residents. You can check out this website to find more special offers near you.

Earlier this year, the Park Service celebrated National Park week with fee waivers from April 17 to April 25.
