Where Bear Canisters Are Required: 2026 Guide
Bear canister regulations are expanding again. Two major new mandates took effect this year: the Pemigewasset Wilderness in New Hampshire now requires IGBC-certified canisters for all overnight visitors (effective May 1), and Olympic National Park has extended its requirement to all wilderness areas, not just specific areas like the Seven Lakes Basin and the Wilderness Coast.
Below are the major U.S. parks, forests, and wilderness areas that require a bear canister, organized on an interactive map. Places where a properly hung food bag satisfies the rules everywhere aren't marked as required. Parks like Glacier and Yellowstone, which provide food poles or lockers at most campsites, are included because a canister is the only compliant option where those aren't provided. Hollow dots mark places where a canister isn't required but the managing agency highly or strongly recommends one. Click any marker for specifics, or use the filters to narrow by region.

What changed this year
The Pemigewasset Wilderness mandate is the bigger story. The Forest Service cited a sharp increase in human-bear conflicts between 2021 and 2025, and declared bear hangs ineffective in the area. Since May 1, every overnight camper has had to store food, trash, and scented items in an IGBC-certified canister, and bear hangs are no longer allowed. The only exception is the Thirteen Falls Tent Site, which has permanent bear boxes. Violations can bring fines or permit revocation. Free canister loans are available at the Lincoln Woods Trailhead cabin and the Pemigewasset, Saco, and Androscoggin ranger stations.
Olympic's expansion is less dramatic but still significant. Previously, canisters were required only in specific areas, most notably the Seven Lakes Basin and the Wilderness Coast. Now the requirement applies to all wilderness areas in the park. Bear wires and self-constructed hangs are not considered compliant.
The broader trend is consistent: Desolation Wilderness renewed its order through 2028, the Hoover Wilderness and Panthertown Valley have added mandates in recent years, and Rocky Mountain NP and Maroon Bells–Snowmass still require canisters for overnight camping. The regulatory map only expands.
Before you go
Confirm current regulations with the managing agency's official website or ranger station. Rules change, sometimes mid-season. This guide was last reviewed in October 2026, but always verify.
It's not just food. Every canister requirement applies to all scented items: toothpaste, sunscreen, lip balm, deodorant, insect repellent, and garbage. If it has a smell, it goes in the canister.
IGBC certification is the minimum threshold, but not always sufficient. Some parks, notably Yosemite and Olympic, maintain their own shorter approved lists. Check before you go.
Rangers do check. In places like Yosemite and now the Pemigewasset Wilderness, visitors without approved canisters can be ticketed. Fines on federal land range up to $5,000.
If you're carrying a canister on more trips each year, it should be comfortable and fit inside your pack. That's exactly what our canister is designed for: it nests against your back, eliminates the barreling effect, and works with your pack, not against it. Sign up for early access →
