If you were planning on hitting the trails around Big Sky this weekend, you might want to pivot. It turns out someone—or something—left a massive “wildlife attractant” (that’s Forest Service-speak for a carcass) right in the middle of some prime hiking real estate.

The Bozeman Ranger District has officially issued a temporary closure for several popular spots in the Custer Gallatin National Forest to ensure you don’t accidentally crash a grizzly bear’s lunch date. Trust us, they aren’t big on sharing appetizers.

The “No-Go” Zone: What’s Closed?

Starting March 18, 2026, through April 15, 2026, the following areas are strictly off-limits to humans:

• Twin Cabin Trail No. 46: Closed in its entirety from the trailhead to the junction with Trail 199.
• Porcupine Trail No. 34: Closed from the trailhead to the junction with Trail 199.
• Forest Trail No. 199: The connecting stretch between the two.
• Forest Service Road 653: Also part of the “stay away” zone.

The closure covers the entire block of National Forest lands bounded by these trails and the east bank of the Gallatin River.

Why the Lockout?

It’s simple: Safety. A “bear attractant” (likely a winter-killed elk or deer) was reported on March 16. In Montana, a free steak dinner on the trail is like a neon “Open” sign for hungry grizzlies coming out of hibernation.

The Forest Service isn’t trying to ruin your spring hiking vibes; they’re trying to prevent a high-stakes wildlife-human encounter. Nobody wants to surprise a 600-pound bear while it’s defending its groceries.

The Fine Print (Literally)

If you’re thinking about “sneaking” past the signs, think again. Violating Order Number 01-11-06-26-02 isn’t just dangerous; it’s expensive. You could be looking at a fine of up to $5,000 or even six months in the slammer. That’s a very high price for a trail run.

Better Alternatives

Don’t let the closure get you down! There is still plenty of Montana outdoor fun to be had. Just head further south toward the park or stick to the west side of the river.

Tip: Always carry bear spray and check for the latest trail updates before you lace up.
