Yellowstone National Park is managed as a natural area to protect plants, wildlife, geology, and scenery. Angling has been a major visitor activity for over a century. Present regulations reflect the park’s primary purposes of resource protection and visitor use. The objectives of the fishing program are to:
- Manage aquatic resources as an important part of the ecosystem.
- Preserve and restore native fishes and their habitats.
- Provide recreational fishing opportunities for the enjoyment of park visitors, consistent with the first two objectives.
In Yellowstone, bald eagles, ospreys, pelicans, otters, grizzly bears, and other wildlife take precedence over humans in utilizing fish as food. None of the fish in Yellowstone are stocked, and populations depend on sufficient number of spawning adults to maintain natural reproduction and genetic diversity. In Yellowstone National Park, we place less emphasis upon providing fishing for human consumption and put more emphasis upon the quality for recreational fishing. Anglers, in return, have the opportunity to fish for wild trout in a natural setting.
Because of the increasing number of anglers in the park, more restrictive regulations have been adopted in Yellowstone. These restrictions include: season opening/closing dates, restrictive use of bait, catch-and-release only areas, and number/size limits according to species. A few places are closed to the public to protect threatened and endangered species, sensitive nesting birds, and to provide scenic viewing areas for visitors seeking undisturbed wildlife.
Permits and Fees
A Yellowstone National Park Fishing Permit is required to fish in the park. Anglers 16 years of age and older are required to purchase either a $18 three-day permit, a $25 seven-day permit or a $40 season permit.
Anglers 15 and younger have two options:
1) Children 15 and younger may fish without a permit if they are fishing under the direct supervision of an adult who has a valid park fishing permit, or
2) Children 15 and younger may obtain a free permit that must be signed by a responsible adult; with this permit, a child can fish without direct adult supervision.
Fishing permits are available at all ranger stations, visitor centers, and Yellowstone Park General Stores. Fishing permits are also available at many businesses in the Greater Yellowstone Area. No state fishing license is required in Yellowstone National Park.
The fishing season begins the Saturday of Memorial Day weekend (usually the last weekend in May) and extends through and includes the first Sunday in November. Exceptions are noted within the Exceptions to General Regulations table within the Fishing Regulations handbook (2.8 MB pdf).Also note that there are areas within the park that are permanently closed to human entry and disturbance, have seasonal area and trail closures, off-trail travel and daylight hour limitations, and party size recommendations.
