I would encourage, however, a bit of caution. National Parks aren’t amusement parks. This may seem obvious, but you’d be surprised how many tourists swagger right up to the bison (even putting their children right next to one to take a picture) or walk right up to the edge of crumbly cliffs or thermal pools. The features of a park are real life and can be really dangerous.

That being said, if you follow the advice of the materials they give you at the gate, mind the signs, and keep your distance from the wild life, you’ll have an experience that you’ll never forget (for all the right reasons).
