Suggestions for a fun trip to Montana- First time

Hello Everyone!!

I would like to plan a wknd trip to Montana for my birthday (Nov 3) with 2 of my best friends. We have never been so looking for any and all suggestions. We would like to do either a cool Air bnb or stay at a ranch. One thing we’d like to do is go horseback riding and just be out in nature and experience the real Montana ( well as much as possible for a short 2 night stay 😂). I’d be flying out from CA and they would be flying from NV. Thank you! 😊
