Yellowstone Fishing License & Permit Guide (2026) — Costs, Rules & Where to Buy
Reviewed by FishKillFlea Editorial Team
Need a fishing license for Yellowstone National Park? You need a special Yellowstone fishing permit — not a Wyoming state license. Here's everything you need to know about costs, rules, and native trout regulations.
Yellowstone National Park has its own dedicated fishing permit system — your Wyoming, Montana, or Idaho state fishing license is NOT valid inside the park. Unlike nearly every other national park in the country, Yellowstone replaces — rather than supplements — your state license. This guide covers permit costs, where to buy, regulations for Yellowstone’s famous native cutthroat trout, and everything else you need to know before wetting a line in America’s first national park.
Yellowstone Fishing Permit Overview
| Permit Type | Cost (2026) | Duration |
|---|---|---|
| Adult (16+) — 3-Day | $18 | 3 consecutive days |
| Adult (16+) — 7-Day | $25 | 7 consecutive days |
| Adult (16+) — Season | $40 | Full season (late May–early November) |
| Youth (15 and under) | Free | Full season (must obtain free permit) |
Important: Youth 15 and under fish for free, but they must obtain a free permit or fish under direct supervision of an adult who has a valid permit.

How Yellowstone’s Fishing Rules Differ from State Rules
Yellowstone has its own unique fishing regulations that override state rules. Key differences:
| Rule | Yellowstone | Typical State Rules |
|---|---|---|
| License required | Yellowstone permit only | State fishing license |
| Season | Late May – early November | Year-round in many states |
| Native cutthroat trout | Catch-and-release only | Often harvestable |
| Non-native trout | Must be killed (not released) | Typically harvestable or C&R |
| Bait | Artificial flies and lures only | Live bait often allowed |
| Lead tackle | Prohibited | Varies by state |
| Hooks | Single barbless hooks only | Barbed hooks often allowed |
Yellowstone’s Unique Conservation Rules
Yellowstone’s fishing regulations focus on protecting native Yellowstone cutthroat trout while eliminating invasive non-native species:
Native Species (Catch-and-Release ONLY)
- Yellowstone cutthroat trout — Must be released immediately
- Arctic grayling — Must be released (rare; found in limited waters)
- Mountain whitefish — Catch-and-release in most waters
Non-Native Species (MUST Kill — Do NOT Release)
- Lake trout — Invasive in Yellowstone Lake; must be killed if caught
- Rainbow trout — Non-native in most Yellowstone waters
- Brown trout — Non-native; must be killed in many waters
- Brook trout — Non-native in most park waters
Why kill non-native fish? Lake trout in particular are devastating the native Yellowstone cutthroat trout population in Yellowstone Lake. By requiring anglers to kill non-native species, the park uses recreational fishing as a conservation tool.

Adjacent State Licenses
If you plan to fish both inside and outside the park, you’ll need separate licenses. As a non-resident, budget accordingly — these are among the most expensive states for visiting anglers:
| Area | License Needed | Notes |
|---|---|---|
| Inside Yellowstone | Yellowstone fishing permit | Independent from state licenses |
| Wyoming (outside park) | Wyoming fishing license | Required for all Wyoming waters outside park |
| Montana (outside park) | Montana fishing license | Park’s north and west entrances border Montana |
| Idaho (outside park) | Idaho fishing license | Park’s west side borders Idaho |

Frequently Asked Questions
Do I need a Wyoming fishing license for Yellowstone? No. Yellowstone National Park has its own fishing permit system. A Wyoming state fishing license is not required and not valid inside the park. However, if you fish in Wyoming waters outside the park, you need a separate Wyoming state license.
How much is a Yellowstone fishing license? A 3-day permit costs $18, a 7-day costs $25, and a season permit costs $40. Children 15 and under fish for free (but must obtain a free permit or fish with a permitted adult). Compare this to state license costs nationwide.
Can I use live bait in Yellowstone? No. Only artificial flies and lures are allowed — similar to the artificial-only rules on many premium trout streams nationwide. Live bait, scented bait, and natural bait are all prohibited to protect native species.
Can I keep fish I catch in Yellowstone? It depends on the species. Native cutthroat trout must be released — Yellowstone enforces strict catch-and-release for all native species. Non-native species (lake trout, rainbow, brown, brook trout) must be killed — you cannot release them. This is a conservation requirement.
When is the best time to fish Yellowstone? Late June through September offers the most consistent fishing. July and August are peak months for dry fly fishing on the Yellowstone River and its tributaries. The season runs from late May through early November.
