Yellowstone National Park, spanning Wyoming, Montana, and Idaho, is a treasure trove of geothermal wonders, wildlife, and stunning landscapes. Below is a curated list of must-see attractions, divided into the North Loop and South Loop, with subsections for geothermal features, wildlife viewing, scenic spots, and other notable points of interest. The North Loop (Mammoth to Norris to Canyon) and South Loop (Canyon to Old Faithful to West Thumb) are based on the park’s Grand Loop Road, which forms a figure-eight. This division assumes you’re exploring by car, as the loops are typically driven in a day each, though hiking and ranger-led programs can extend your visit.
