Goat Haunt to Two Medicine in Late October: Glacier's Last High Traverse

This report covers the long cross-park line from Goat Haunt at the head of Waterton Lake, up through Granite Park Chalet, over Pitamakan Pass, and out toward Dawson Pass and Two Medicine. The elevation data for this traverse runs about 55 miles with roughly 9,000 feet of total gain, starting at 3,150 feet at Goat Haunt and topping out near 8,100 feet. That's a big number for total gain on a route that doesn't lose much net elevation, so budget real days for it, not just miles.\n\nGlacier runs backcountry camping under one park-wide reservation, the Wilderness Permit, booked through Recreation.gov. It's a zone-based system, meaning you reserve a chain of designated campsites for your nights out rather than just a general area, and it covers everything from Goat Haunt to Two Medicine under the same application. Cost is a flat $10 application fee plus $7 per person per night, which adds up fast on a trip like this with multiple camps strung along the route.\n\nLate October sits at the edge of the backcountry season here. Granite Park Chalet and other visitor services are closed for the year by this point, so don't plan around resupply or indoor shelter at that stop, it's a trail junction and campsite only now. The Goat Haunt approach normally depends on the boat shuttle across Waterton Lake from the Canadian side, and that service typically wraps up for the season well before late October, so check current access before counting on it. If the boat isn't running, you're looking at a much longer walk-in from the Waterton townsite or an alternate entry point.\n\nConditions at elevation get wintery fast this time of year. The high ground around Pitamakan and Dawson passes, both above 4,400 feet on the ridgeline and climbing toward that 8,100-foot high point, can hold snow and ice well before the calendar says winter. Microspikes and trekking poles earn their keep here even on a route that reads as a summer classic. Days are short too, so plan camp-to-camp mileage with a few hours of headlamp time built in as backup, not as the plan.\n\nWater along the route comes from the same streams and alpine lakes that feed it all summer, including the flow right at Goat Haunt, but treat everything regardless of how clear or cold it looks. Flows are typically lower in fall, so don't assume every seasonal trickle marked on older maps is still running.\n\nBears are still active and feeding heavily ahead of denning season, so food storage rules aren't relaxed just because the crowds are gone. Every backcountry site in the park requires hard-sided canister storage or use of the provided poles and cables, and rangers do check. Bring a canister even if you're used to hanging food elsewhere.\n\nThe most common mistake on this kind of late-season traverse is treating it like a summer itinerary with a jacket added. The mileage and gain numbers alone make for long days, and a few inches of fresh snow on a pass can slow a strong hiker to half pace. Build slack into the schedule, confirm your zone permit nights match a realistic camp spacing, and have a bailout plan if weather closes in over the high passes.\n\n— Compiled by the PermitSnag team from agency info, ranger updates, and public trip logs.
