I am a French citizen with a B2 visa and I plan to stay for ~6 months in the US.

As I'll be hiking the Continental Divide Trail, I'd like to leave North America from Calgary Airport. I know that US and Canadian citizens have a simplified procedure to cross the border at Glacier National Park:

There is a US ranger station and customs post at Goat Haunt for south bound people into the US. It is a Class B Port of Call, which just means it is for US and Canadian citizens and permanent residents only. Northbound there is an RCMP post in Waterton townsite. Because of the twin park structure you do not seem to need to check in with the Mounties, as people take the boat down to Goat Haunt and walk back all the time. So, as a short answer I think you are ok just walking across.


Or this Reddit topic.

But I can't find reliable sources for a non-US/Canadian citizen.

I'd prefer to cross the border at Glacier NP, because if I have enough time I'd like to continue hiking in Canada, taking the Great Divide Trail to get closer to Banff and Calgary.

I think I'd stay between up to 2 or 3 weeks in Canada, maybe less if I'm late on my hiking schedule.

    Just to note a potential confusion. If you're talking to Canadians about "Glacier National Park", they might think you mean the one in British Columbia, which is about 300km from the American one. Commented Dec 12, 2017 at 14:11
  • @DavidRicherby Good point. The combined entity is called Waterton-Glacier International Peace Park, and would be the less ambiguous way of referring to them. It is a few hours' drive between Glacier N.P. (MT, US) and Glacier N.P. (BC, CA). Commented Dec 12, 2017 at 14:39

This is the customs and immigration office, if you cross inside the park. (There is a highway border crossing along the east margin of the park, at Chief Mountain, that would be a perfectly suitable place to cross for certain.)

If you are going to be hiking when you cross into Canada, it looks like you can submit to inspection here. You should call the boat operator (you'll be arriving by boat, it appears) to see if this is a problem, and to inquire about how to secure tickets. (I think they normally provide a round trip from Canada.)

If you want to talk to Canada Border Services Agency to check first (and I recommend you do), you can contact them via numbers listed here https://www.cbsa-asfc.gc.ca/contact/bis-sif-eng.html . At the time of posting, there is a toll-free number that will only work in Canada and the US, and two numbers you can dial from overseas - the area code 204 number is in Winnipeg, much closer than the other (New Brunswick) and would probably be the more suitable one.

To clarify, the Canadian customs office is not really an office; you report by telephone. If CBSA wants to inspect you, they will have you wait on the boat for their arrival. You will not be allowed to disembark until approved or inspected.

    Thanks for the answer. I'll be by foot (there is a path left of the lake ; the official end of the CDT is right at the border. The first village I will encounter in Canada is Waterton.

    Note that all services of the Canadian federal government are supposed to be offered in French as well as in English, so you can request to speak with a francophone agent when you call if you prefer. Commented Dec 11, 2017 at 16:02

    @MichaelSeifert Good point, and if the 506 number rings to Moncton or francophone New Brunswick, the odds of a bilingual agent there are pretty good, although there is a pretty sizable francophone community in Winnipeg, too. Commented Dec 11, 2017 at 16:08
  • @Shan-x This crossing is a water crossing only, so if you are on foot, you are best to call CBSA and ask if that is acceptable, and if so, how to report. Commented Dec 11, 2017 at 16:09

    Please get all your ducks in a row before you try to cross. You do not want to have to say that you were ever denied entry to a country!

Jim MacKenzie's advice to contact the CBSA directly is probably the best course of action. If you do so, please come back and post their advice as an answer to your own question so that other people can see it in the future.

That said, if it turns out to be impossible to cross the border at Waterton Lake, you have another option. The Continental Divide Trail (on the US side) branches into two forks near Lake Sherburne (as can be seen on the map here.) One fork goes to Waterton Lake; the other goes to the highway border crossing at Chief Mountain. Moreover, Tamarack Mountain Outfitters offers a daily shuttle service between the Chief Mountain border crossing and the Waterton, AB townsite. The Chief Mountain border crossing is a "normal" border crossing, and is open during daylight hours during the summer.

Of course, the spirit of thru-hiking is generally that you don't want to get off the trail if you can avoid it; however, there are other options available should they be necessary.


First from your quoted info

It is a Class B Port of Call, which just means it is for US and Canadian citizens and permanent residents only.

This doesn't appear to be true. From the CBP site:

Class B means that the port is a designated port of entry for travelers who at the time of applying for admission are lawfully in possession of valid Permanent Resident Cards or valid non-resident aliens' border-crossing identification cards or are admissible without requiring a waiver of inadmissibility.

So it is not just for US and Canadian citizens.

The National Park Service pages on Glacier have several pages on international crossings, but they deal more with travel south into the US. Even so, they reference crossings here by foot and confirm that normal procedures should be to call the Canadian folks after crossing.


Welcome to the first International Peace Park in the world! Glacier National Park in the United States and Waterton Lakes National Park in Canada combined in 1932 to become the Waterton-Glacier International Peace Park. This designation allows backpackers to hike continuously from one country into the other through an area known as "Goat Haunt."

When entering Canada from the U.S. you must call Canadian Customs at (403) 653-3535 for acceptance/rejection by Canadian authorities as soon as you arrive in Waterton Townsite. Read all the details under "Entry and Exit Information for Goat Haunt" on our trail status page!

Trail Status Page (https://www.nps.gov/glac/planyourvisit/trailstatusreports.htm)

Entering Canada at Waterton Townsite

Waterton Townsite is NOT a Canadian Port of Entry therefore all arrivals to Waterton Townsite must phone Canadian Customs without delay at (403) 653-3535 or (403) 653-3009 for acceptance/rejection by Canadian authorities. More Information on contacting Canadian Customs is available at the Waterton Lakes Visitor Centre or the Waterton Station of the Royal Canadian Mounted.

    Note that the last page you link to says this about entries at Goat Haunt: "Citizens from countries other than Canada or the United States must present a valid passport and a current I-94 or an I-94W." The CBP page is probably saying this too, just in obscure language. Not that it matters since the OP is going north.

U.S. Customs pilot project expands to Waterton Lakes National Park

By Tom Roulston Global News

Posted June 13, 2018 7:11 pm

U.S. Customs and Border Protection (CBP) is rolling out a new pilot program in Waterton Lakes National Park for pedestrians who will be crossing the Canada-U.S. border into Glacier National Park.

The Reporting Offsite Arrival-Mobile (ROAM) application, available for Apple and Android devices, will allow park visitors crossing into the U.S. via boat or on foot the ability to report their arrival to Customs officials remotely.

The program will launch on June 16 with four inspection kiosks stationed at the Waterton Cruise Company dock.

There, travellers can create a profile and declare their intended trip to the United States.

The ROAM app will also give boat passengers and hikers the option of reporting their arrival from any location via their smartphone.  The app enables a video conference with CBP officers.

It's better quote news article from CBP themself. I emphasize "backcountry" for you.

CBP expands ROAM app pilot to Glacier National Park | U.S. Customs and Border Protection

SWEETGRASS, Mont. — U.S. Customs and Border Protection Office of Field Operations is pleased announce the addition of Waterton, Alberta, to the list of pilot locations now using the new Reporting Offsite Arrival-Mobile (ROAM) application for pedestrian reporting.

ROAM app

CBP has expanded it's ROAM app pilot
program. This pilot expansion includes
pedestrians traveling to Goat Haunt,
Montana, via the International Cruise
Line and/or backcountry hiking trails
via Waterton International Peace Park
in Alberta, Canada, and Glacier National
Park in Montana.

This pilot expansion includes pedestrians traveling to Goat Haunt, Montana, via the International Cruise Line and/or backcountry hiking trails via Waterton International Peace Park in Alberta, Canada, and Glacier National Park in Montana.

This pilot addresses a pressing issue for border waters and backcountry trails that depend heavily on tourism. Vacationers and outdoorsmen from around the world travel to these border areas with their families to enjoy both countries’ national parks. Oftentimes these groups travel into the United States by way of the Waterton Shoreline Cruises in Waterton which requires checks by U.S. Customs and Border Protection at the Goat Haunt Port of Entry when the intent of the traveler was to cross into the United States and hike backcountry trails in Glacier National Park

The new pilot program will launch on June 16 at Waterton Cruise Company, which docks in Waterton. It is designed to allow travelers intending to cross into the United States via the international cruise line to be inspected by U.S. Customs and Border Protection through the ROAM application. Four inspection kiosks will be stationed at the Waterton Cruise Company docks for travelers to create a profile and declare their intended trip into the United States.

The ROAM app allows boat passengers and hikers the flexibility of reporting their arrival into the U.S. from any location via a device that is capable of 4G/LTE or Wi-Fi. The ROAM app is available in the Apple and Android stores under CBP ROAM. The ROAM app enables a video conference with CBP officers to efficiently make entry into the U.S.

Intending visitors to the United States can construct a profile within the application, and submit their information for a CBP video conference while at the docks, waiting to board the International vessel. Traveler information can be easily saved within the app, or recreated for future crossings.

CBP's remote arrivals app to launch nationwide -- FCW

A new mobile app from Customs and Border Protection will make life easier for pleasure boaters and hikers in border areas, while freeing up border agents for enforcement operations.

CBP hopes its Reporting Offsite Arrival-Mobile (ROAM) app will be useful for small boat operators and their passengers, as well as hikers and other outdoors enthusiasts, who enter U.S. waters and territories in their travels in border regions.

The app is for travelers who want to be processed by CBP upon entry into the U.S.

"Most travelers want to be compliant" with immigration law, and the app makes it easier to do that, said Christopher Wright, program manager for CBP's office of field operations--innovation.

Use of the app by travelers will free up agents to enforce immigration rules against travelers who don't want to comply, according to Wright. The app "is more a reallocation" of agents from compliance work to enforcement, he said.

The app works on LTE- or Wi-Fi-capable mobile devices and allows CBP agents to initiate a video chat after travelers set up a login and profile. Wright said CBP has also partnered with Wi-Fi-equipped local businesses in remote areas where cell coverage is limited and set up kiosks at those businesses.

ROAM replaces CPB's Outlying Area Reporting Stations (OARS), which uses 90's era, one-way video transmission capabilities and speakerphones at remote marinas and docks. Those systems, according to the agency, are outdated and challenging to access.
