This week in Yellowstone National Park, from June 18th to June 24th, 2026, I will tell you why now is the time to hit up a specific lake in the northern range, give some tips on how to avoid the summer crowds, and share some history of an expedition before the park was the park. I will also give you the complete weather forecast, a cool trail to hike, the snowpack update, the wildlife report, and everything else you need to have an incredible time, “This Week in Yellowstone.”
