Alberta's Chief Mountain border crossing has officially opened for the 2026 summer season, providing travelers with a scenic route between Alberta and Montana. The seasonal crossing, operated by the Canada Border Services Agency (CBSA), will be open daily from May to September, weather permitting.
Seasonal Operations and Benefits
The Chief Mountain border crossing is a popular alternative to the busier Carway and Coutts crossings, offering stunning views of the Rocky Mountains. It is typically open from late May to late September, but exact dates depend on weather and road conditions. The crossing is open from 7 a.m. to 10 p.m. Mountain Time during the summer months.
Travel Advisory
Travelers are advised to check the CBSA website for current conditions and wait times before heading to the border. The crossing is accessible via Highway 5 in Alberta and Montana Highway 17. All standard border crossing requirements apply, including valid passports or other approved travel documents.
The opening of the Chief Mountain border crossing is a welcome development for tourists and locals alike, providing a direct link to Waterton Lakes National Park in Alberta and Glacier National Park in Montana. Both parks are popular destinations for hiking, camping, and wildlife viewing.
In addition to the Chief Mountain crossing, Alberta has several other border crossings that operate year-round, including the Carway and Coutts crossings. Travelers are encouraged to plan their trips accordingly and to be prepared for potential delays during peak travel times.
