Idaho Fishing Licenses: What, Where, How Much (2026)

Who needs a license

Idaho law requires anyone 14 years or older to hold a valid Idaho fishing license to fish in state waters. Children under 14 fish free under a parent or guardian’s license but have their own separate creel limit. Visiting anglers (out-of-state residents) need a nonresident license; Idaho residents need a resident license. There is no "tourist visa" or general state-park-only fishing pass — you need a license.

Note: Yellowstone National Park has its own separate fishing permit system. An Idaho license is not valid inside the park, and a Yellowstone permit is not valid in Idaho. If you plan to fish both, you need both. See the Yellowstone section below.

In person, in Island Park

Most local outfitters and general stores sell licenses. Reliable in-person vendors:

• TroutHunter (Last Chance)
• Henry’s Fork Anglers (Last Chance)
• Mack’s Sport Shop
• Pond’s Lodge front desk
• Most general stores in Island Park, Ashton, and West Yellowstone (Montana stores can sell Montana licenses but not Idaho licenses — verify before buying)

In Idaho Falls or Rexburg (en route)

Sportsman’s Warehouse, Cabela’s, and many sporting goods stores along US-20 sell Idaho licenses. If you’re driving up from the airport, this is the easy stop.

If you're also fishing inside Yellowstone

Yellowstone National Park has its own separate fishing permit. An Idaho license is not valid inside the park. You need both if you plan to fish both waters.

Yellowstone fishing permits (2026)

Per the National Park Service (nps.gov/yell/planyourvisit/fishing.htm):

• 3-day: $40
• 7-day: $55
• Season: $75
• Children 15 and under: free with permit

Yellowstone’s fishing season opens the Saturday of Memorial Day weekend and runs through the first Sunday in November. Specific waters have specific opening dates — the Madison River opens later, for example.

Park-specific rules

• Barbless hooks only on all park waters
• No lead weights or lead-based tackle
• Native species (Yellowstone cutthroat, Westslope cutthroat, mountain whitefish, Arctic grayling, native chub species) are catch-and-release only
• Non-native species (rainbow trout, brown trout, brook trout, lake trout) are subject to specific possession limits and in some waters mandatory kill (lake trout in Yellowstone Lake)

Buy at any park entrance, visitor center, or general store.

Key rules to know before you cast

License must be on your person

Carry a printed copy, a saved PDF on your phone, or the physical card. Conservation officers do check, especially at popular access points on the Henry’s Fork.

Section-specific rules on the Henry’s Fork

• Big Springs: closed to fishing year-round
• Harriman State Park (Railroad Ranch): fly-fishing only, catch-and-release, barbless hooks
• Box Canyon: catch-and-release for rainbow trout
• Below Mesa Falls: different rules; verify in the current rule book

Reading the current rule book

Idaho fishing rules change year to year. The 2026 fishing rule book is published annually by IDFG and available free at every license vendor and online at idfg.idaho.gov/rules/fish. Read the section for the specific water before fishing.

Enforcement

Citation rates are higher on the Henry’s Fork than on most Idaho waters — it’s a high-visibility fishery. Fishing without a license is a fine plus loss of license privileges. Fishing in closed waters (Big Springs) is heavily enforced. The Citizens Against Poaching tip line is 1-800-632-5999 — for reporting violations.

Questions, answered

Do I need a license to fish in Henry’s Lake State Park?

Yes — Idaho fishing license required. Henry’s Lake is in Idaho.

Do I need a license to fish in Yellowstone?

Yes, but it’s a separate NPS permit, not an Idaho license.

Can I fish on my own private water without a license?

Generally yes if it’s entirely contained on your own private property and not connected to a public waterway. The Henry’s Fork and its tributaries are public waters even where they flow through private land.

What if I’m guided?

You still need a license. A guide does not provide the license — some guide services include the cost in the package, but the license is in your name.

What about kids under 14?

Under 14 fish free in Idaho under a parent or guardian’s license. They have their own separate limit.

I’m a veteran with a disability rating — is there a discount?

Idaho offers a discounted Disabled American Veteran (DAV) license for veterans with a 40% or higher service-connected disability rating. Available to both Idaho residents and nonresidents. Documentation required.
