Now that spring has officially sprung, it's high time to go on an adventure.
The Department of the Interior's rapidly growing Instagram account has been featuring stellar shots of sunrises and sunsets that showcase America's natural beauty. The National Park Service, a division of the DOI, oversees more than 400 sites (you can find one to visit here) and the DOI manages 500 million acres of public lands.
The National Park Service is celebrating National Park Week starting Saturday, April 18. All national parks -- including heavyweights like Yosemite, Glacier and Acadia -- are waiving entrance fees for the weekend to encourage everyone to get out there and find their park.
Take a look at some of the stunning images below. You can follow along throughout the year @usinterior.
