We are heading from Wisconsin to Cottonwood Campground (Theodore Roosevelt Park, ND) on August 10. We will then be heading to Yellowstone for our destination at Grant Campground on Saturday August 11. We plan on unhooking our camper and use the campground as a hub for our day trips each day. We would like to see as much of Yellowstone as we could from August 11 through August 16th. We have 3 children ages 13, 11, and 7. We enjoy the outdoors, hiking, waterfalls, and wildlife. We are very excited to see the geysers. The longest round trip hike that my youngest could do is approximately 5 miles per hike. We enjoy waking up early and paths with less people. Is there days/times that you experience less people in Yellowstone or is it quite busy no matter what? We are first time Yellowstone visitors and would appreciate as much help as we can get to make this trip as efficient and fun as we can. Thank you in advance for any opinions/recommendations that you are able to give.
