A) We visited the Grizzly & Wilf Discovery Center in West Yellowstone the afternoon we arrived and really enjoyed it.
B) Three Bears for dinner - had good steak and great atmosphere.
Old Town Cafe was recommended by locals for breakfast - it was fantastic and their special recipe syrup was amazing. I’ve also heard Running Bear Pancake Lodge is great.
C) There’s lots of great activities in the Big Sky region. We opted to do a morning escape room that goes up the mountain by ski lift, does an escape room in a cabin up there, and then a hike down the mountain.
If in Bozeman, I highly recommend the Museum of the Rockies (especially if you have dinosaur fans like my husband - largest collection of dinosaur skeletons in the world) and we also really enjoyed the Computers & Robotics Museum (a really small museum but a fantastic collection of Apollo computers).
