I'd recommend https://www.google.com/travel/flights to find competitive prices with all the different airlines. You can either fly into Calgary, AB or Cranbrook, BC. The drive from Calgary is absolutely gorgeous, taking around 4.5 hours. Kimberley is only 15 mins from the Cranbrook airport. You can get a rental car at either airport, but they need to be returned to the same airport they originate from.
Hoping those of you that are traveling in will take advantage and explore the area and take in the sights. Kimberley is surrounded by national parks, charming mountain towns, bike and hiking trails, lakes and rivers. Our small town has many local shops and restaurants to enjoy.
The Larix is a beautiful boutique hotel located downtown Kimberley, on the edge of the Platzyl. There are a handful of rooms on hold, so just say Ruby/Crowe wedding. This is really the only hotel accommodation in Kimberley, so if you are not planning on camping or Airbnb/VRBO, then don't delay to book!
Another alternative to camping or staying in a hotel is airbnb.ca. There is a great selection of accommodations to choose from in the Kimberley area. Anywhere in the Kimberley and Marysville areas are close enough to stay. There are a limited number of log homes on Airbnb that are located quite close to the wedding venue, so if that is your preference use the map function when searching and it will be the area located up St Marys Lake Road. There are options for accommodation up near the skill hill as well, which is very close to where we live.
