See Yellowstone

• Old Faithful and the Upper Geyser Basin: eruptions roughly every 60 to 110 minutes; check predictions at the visitor centre.
• Grand Prismatic Spring: best seen from the Fairy Falls overlook trail.
• Grand Canyon of the Yellowstone: Lower Falls and Artist Point.
• Lamar and Hayden valleys: bison, elk and, with luck and binoculars, wolves and bears, best at dawn and dusk.

The private vehicle fee is US$35 for 7 days. Since January 1, 2026, visitors who aren't US residents and are 16 or older pay an extra US$100 per person at Yellowstone and 10 other popular parks, unless they buy the US$250 non-resident annual pass. Bring US ID if you live in the US.

In-park lodges and campgrounds book out up to a year ahead for summer. Gateway towns include West Yellowstone, Gardiner, Cody and Jackson (for a combined trip with Grand Teton). The park is huge: allow time, as driving between areas takes 1 to 2 hours.

• $ to $$: camping and groceries, sharing a car: about US$60 to $120 a day
• $$$: park lodges or motels in gateway towns: about US$200 to $350 a day
• $$$$: guided wildlife safaris and premium lodges: US$400+ a day

• Stay at least 100 yards (91 m) from bears and wolves and 25 yards (23 m) from bison and elk. Bison injure visitors every year.
• Stay on boardwalks in thermal areas; the ground can be thin crust over boiling water.
• Carry bear spray on trails and know how to use it.
