It might be fall, but now is a good time to start planning your summer trip to Yellowstone National Park. Yellowstone hosts over 4 million visits a year and more than half of these happen June-August. Arrive early, stay late and if you walk half a mile from your car, you’ll leave the crowds behind (in most cases). And be sure to take the #YellowstonePledge to protect this park for current and future generations. Summer photo of Trout Lake by Jacob W. Frank, National Park Service.
