Yellowstone - west or northwest enterance?

Would like to avoid steep grades.

Any particular reason why? That might help get some more relevant answers.

I’d enter, or leave, the park from a direction you haven’t taken previously. I don’t seek the easy way but rather the interesting way.

That would be us, too, unless there's a concrete reason why you can't. I've entered twice from the west and once from the east. It's a different experience each way and each time.

I'm sure there are those that seek steep grades just for the fun of it, however, I'm not one of them. As per my OP I'm just looking for a choice between the two entrances I mentioned.

My truck, pulling my fifth wheel, generates a lot of heat in the transmission on extended uphill grades. Also, I do not have an exhaust break so coming down a steep grade can be a challenge.

I've never been to Yellowstone before so any entrance will be a nice experience, but I prefer to take as gentle approach as possible.

My hope was that Hwy 89 through Gardiner would work as that would be closer in distance for me. Without knowing the road it's a difficult decision. Based on the above responses it looks like Hwy 191, although be a little longer distance may be my best route. Thanks for the input.
