The National Parks are free next week.
More 300 National Park Service sites are offering free admission as part of National Park Week.
Some of the nation's most popular National Parks are included, like Yellowstone in Wyoming and Montana, Yosemite in California and Rocky Mountain National Park in Colorado.
Officials at the Colorado park say visitors will be able ski at higher elevations and hike in the lower portions were the snow is melting.
If you can't make it to a National Park next week, another freebie is coming up on the first day of summer, June 21.
