    This was the year Instagram grew up. The no-longer-only-square photo app added 100 million users, rolled out innovative ads to leading brands, and became a booming business for pro athletes, photographers, and other “influencers.”

    The upside of all that growth? Innovative shots. And lots of data. To take advantage of both, we teamed up with Instagram to determine the most-photographed national parks of 2015. Here we present our favorite images from the 25 parks that appear most frequently in your photo feed.
