This post is part of my series on great road trips from Denver.

With four days you have the option of heading a little further afield, either into Utah (see what to do with one week) or up to Yellowstone National Park. Yellowstone is a really spectacular and unique place, combining great scenery, lots of wildlife including more buffalo than you will see anywhere else, and many interesting geothermal features from geysers (including the famous Old Faithful) to bubbling mud pools.

A couple of nice places to stay inside the Park, if you book early enough, are Old Faithful Inn and Lake Yellowstone Hotel. Or there’s a good range of places to stay, including plenty of cheaper options, in West Yellowstone. For a 4 day itinerary I would recommend:

  • Day 1: drive from Denver to Jackson, Wyoming (about 10 hours?) and spend the night there. Jackson is an interesting little western style town, also home to the well known ski resort of Jackson Hole.
  • Day 2: drive north from Jackson through Grand Tetons National Park, which has spectacular mountain and lake views. This brings you into the south side of Yellowstone and you’ll be able to take in the famous Old Faithful Geyser, which erupts every 90 minutes. And you’ll have plenty of chances to see other sights in Yellowstone en route to wherever you’re staying.
  • Day 3: more Yellowstone exploring
  • Day 4: a full day’s drive back to Denver, I would suggest driving out of the east entrance of Yellowstone to see something different, or you could retrace your route through Jackson.

Yellowstone really is an extraordinary place, and very highly recommended.
