There are several great option to consider, depending where you travel from and how much time you have. Flying into Cranbrook (YXC) is a great option for getting to the ranch as fast as possible. Both Air Canada and Pacific Coastal offer service into Cranbrook multiple times per day via Calgary and Vancouver. We do offer a free shuttle to and from the Cranbrook Airport.
Another Canadian option is flying into Calgary, Alberta (YYC) and driving to the ranch. You could extend your vacation and drive through Banff National Park and Lake Louise. This northern route offers incredible recreational opportunities, if you have an extra night or two. Banff and Lake Louise offer, including many different hiking trails. Roads conditions are usually very good and there are lots of great hotels and resorts in the Banff Nation Park. I personally like the Rim Rock Resort, just outside the town of Banff. It is a 4.5-hour drive from the Calgary airport to Three Bars Guest Ranch.
Vancouver is another option if you are taking an extended vacation. It is a 10-hour drive from Vancouver to Three Bars Guest Ranch, so it is best to break it up into a few days. There are many things to see and do along the way; several national parks, vineyards, lakes, etc.. This route gives you the option of travelling north on Hwy 5 and Hwy 1, or taking Hwy 3 along the southern route of the province.
If you are travelling from the U.S., we suggest considering both Spokane, WA (GEG), and Kalispell, MT (FCA). You can usually save money by flying within the U.S. rather than internationally into Canada. Spokane is a 3.5 hour drive to the ranch and Kalispell is only 2 hours to the ranch. The great thing about Kalispell is that it is at the south gates of Glacier Park, another great add on if you have a couple of extra days in your holiday plans. Whitefish, MT is also close and a great little town.
Rental Cars: It is not necessary to have a rental car while at Three Bars Guest Ranch, however, it is sometimes more affordable to keep your car than to pay the drop fees. Also keep in mind that any car rented in the U.S. will have to be returned to the U.S. and the same applies to Canadian rentals. You cannot return a rental car to a different country.
Passports: it is necessary to have a passport to travel into Canada.
