Airports:
Depending on the time you have or areas you'd like to see on your way to the wedding, there are a couple different options
Billings, MT ~1 hr 30 min to Nye
Bozeman, MT ~2 hr 15 min to Nye
Cody, WY ~2 hr to Nye
Rental Cars:
Renting a car early is recommended! Billings and Bozeman airports have been known to have rental car shortages in the busy season.
Turo is also available in Billings and Bozeman, and a good alternative to the rental options at the airports
Planning your stay:
Nye is about 45 minutes from a grocery store and coffee hut! Absarokee has a small grocery store and some restaurant options, but your choices are a bit minimal after that.
The Nye Trading Post has a small spread of snacks/drinks, and a pop up pizza stand. I believe they will be open for the season, TBD. Carter's Camp is a small bar down the road from the venue, as well.
Hiking:
There are a couple trailheads in Nye (Woodbine Falls, Sioux Charley, West Fork Stillwater Trailheads) Mystic Lake Trailhead is a littler farther away, but a beautiful trail.
