This week in Yellowstone National Park, from April 23rd to April 29th, 2026, I will let you know about the return of the red dogs, give some advice about trying to do all the open sections of the park in a day, share a birthday celebration of sorts for an iconic park location, and hope to convince you to trek in a geyser basin. I will also give you the complete weather forecast, the snowpack update, the wildlife report, and everything else you need to have an incredible time, “This Week in Yellowstone.”
