The National Park Service has closed all of Many Glacier Valley in Glacier NP due to flooding, including every CDT-area trail inside it (MM 3001-3012.5). Do not enter. If you're in the valley, follow NPS direction and get to safety.

The NPS closed the entire Many Glacier Valley to the public today for safety, including the Many Glacier Hotel, Swiftcurrent Motor Inn, and Many Glacier Campground.

CDT-area trails inside the closure (~mi 3001-3012.5):

• Swiftcurrent Pass Trail, Campstore parking lot to Swiftcurrent Pass (~mi 3006.5-3012.5)
• Piegan Pass Trail, Many Glacier Hotel to Featherplume Falls jct (~mi 3001-3003.5)
• Saddle Horse Corral Trail, ~mi 3003.5 to mile 1 of the East Chief Mountain route
• Swiftcurrent Lake Loop, ~mi 3003.5-3004

A National Weather Service Flood Watch is in effect through this evening (Mon, June 29) with heavy rain, fresh snow up high, swift and cold creek crossings, and real hypothermia risk. The alpine section of Going-to-the-Sun Road (Avalanche to Jackson Glacier Overlook) is also closed for weather. No reroute is available yet and conditions are changing fast.

If you're hiking this stretch: do not enter the valley. Sit tight, let the weather move through, and check the NPS trail status page before you commit to anything in Glacier.

UPDATE (6/9/2026): Good news! GNP has reopened the CDT along the Chief Mountain route (miles 7.5-17.5), much earlier than anticipated!

Please continue to practice bear safety and awareness. Continue to monitor GNP trail closures page and CDT alerts page, as occasional wildlife closures are typical.

ORIGINAL POST (6/8/2026): Miles 7.5 - 17.5 of the trail is closed due to bear activity. There is no re-route in place. Please avoid the area, and consider hiking other portions of the CDT or wait until the closure is lifted.

The park estimates this closure may be in place until June 18th, however this is difficult to predict. Keep on eye on the GNP trail status page for updates:
https://www.nps.gov/glac/planyourvisit/trailstatusreports.htm

The Waterton route is currently open but sites remain in winter status and much of the trail is still under snow. CDT southbounders may want to consider pushing back their start dates or hiking other portions of the CDT.

⚠️TRAIL ALERT: A portion of the Continental Divide Trail in Yellowstone National Park (CDT miles 2033-2039) is closed until further notice following a bear encounter on May 4 in which two hikers were injured.

The Summit Lake Trail, which carries the CDT through this section, is closed within the affected area.

No reroute is available at this time; hikers in the area should plan to avoid the closure entirely until the National Park Service lifts it.

A few reminders for traveling through bear country:

• carry bear spray and know how to use it,
• hike in groups of three or more,
• make noise on the trail,
• stay 100 yards from bears at all times,
• avoid hiking at dawn, dusk, or at night when grizzlies are most active.
