What state is Yellowstone in? Yellowstone National Park occupies space in Wyoming, Montana, and Idaho, though it is not evenly split between all three of these states. In fact, Yellowstone is primarily located in Wyoming, with over 90% of the park located in this state. After Wyoming, less than 5% of the park is in Montana, with the final 1% found in Idaho.

There are five distinct entrances into Yellowstone National Park. This gives you plenty of options when it comes to reaching the park and traveling through it. Yellowstone is ideal for summer road trips and National Park exploration, with nearly 500 miles of paved road to travel over. This means you can enter the park from the west and depart from any other direction should you so choose.

One important thing to note as you plan your Yellowstone National Park visit is the elevation gains found throughout the park. Yellowstone varies in elevation, from 5,000 feet all the way to 11,000 feet. However, the tallest park elevations are found at mountain peaks, only accessible via hiking trails. This means you shouldn’t have to worry about driving quite that high, though the park averages 7,000-8,000 feet in elevation!

Yellowstone National Park is open year round, though some roads close down seasonally. In fact, only the northernmost entrance and northeastern entrance remain open to tourist traffic during the winter season, which begins promptly on November 1st. The road between these two entrances remains open, but all other roads close throughout the park during this time.

This isn’t to say that you can’t access the rest of Yellowstone during this time of year. In fact, the park offers a number of oversnow activities starting December 15th. This means that you can rent motorized snowmobiles or hop on an oversnow coach tour in order to see the rest of the park safely and securely!

All roads in, through, and out of the park open by June 1st. This means that you can fully access every single mile of Yellowstone National Park during the months of June-October. While weather may make these dates subjective, Yellowstone is no stranger to cold weather and snow. However, it still means that you should plan on traveling slowly and safely, should you choose to visit during the winter months!
