A three-day license lets you fish in Idaho for three consecutive calendar days without buying a full-year permit
Idaho's three-day fishing license is a short-term option for visitors or locals who want to fish for a few days without committing to an annual license. You purchase it for three consecutive calendar days — the license becomes valid the day you buy it and expires at the end of the third day. The cost is significantly lower than an annual resident or non-resident license, making it practical for weekend trips or short vacations.
The three-day license covers the same species and waters as a full-year license: trout, steelhead, salmon, bass, walleye, pike, and panfish in Idaho's rivers, lakes, and reservoirs. You must still follow all state regulations for bag limits, size restrictions, and seasonal closures that apply to the water you're fishing. The license does not exempt you from purchasing additional stamps or permits if you're targeting specific species like steelhead or salmon.
Key Takeaways
- A three-day license costs less than a full annual license and covers three consecutive calendar days starting the day you purchase it.
- You can buy a three-day license online through the Idaho Department of Fish and Game website, by phone, or at authorized vendors throughout the state.
- The license covers all freshwater species in Idaho but does not include required stamps for steelhead or salmon, which you must purchase separately.
- Non-residents and residents pay different rates; non-resident three-day licenses cost more than resident ones.
Where to Buy a Three-Day License
The fastest way to get a three-day license is online through the Idaho Department of Fish and Game website at idfg.idaho.gov. You can purchase and print your license immediately, and it becomes valid right away. The online process takes about five minutes and requires your name, address, and date of birth.
If you prefer to buy in person, authorized vendors across Idaho sell three-day licenses — these include sporting goods stores, tackle shops, and some outdoor retailers. Call ahead to confirm the vendor has them in stock. You can also purchase by phone through the Idaho Department of Fish and Game during business hours, though this method is slower than online purchase.
Cost and Resident vs. Non-Resident Rates
Idaho charges different rates for residents and non-residents. Resident rates are lower because residents pay state income tax and contribute to fish and game funding year-round. Non-resident rates reflect the cost of managing fisheries for out-of-state visitors. Both rates change periodically, so check the Idaho Department of Fish and Game website for current pricing before you buy.
The three-day license is one of the cheapest ways to fish legally in Idaho for a short period. If you plan to fish more than a few days per year, an annual license may cost less per day of fishing over time, but the three-day option requires no commitment and no waste if you only fish once.
What the License Covers and What It Doesn't
A three-day license allows you to fish for all freshwater species in Idaho during the open seasons for those species. You can fish trout, steelhead, salmon, bass, walleye, pike, and panfish in any open water. You must follow all bag limits, size restrictions, and seasonal closures — these vary by species and by water body, so check the current Idaho fishing regulations before you go.
The three-day license does not include stamps for steelhead or salmon. If you want to keep steelhead or salmon, you must buy a separate steelhead stamp or salmon stamp in addition to your three-day license. These stamps are sold at the same vendors and online. You also do not need a three-day license if you are fishing on private land with the owner's permission and only for personal use, though this exemption has strict limits — check with the Idaho Department of Fish and Game if you are unsure.
How to Use Your License When You're on the Water
You must carry your license with you at all times while fishing. If you printed it at home, keep the printed copy in your pocket or pack. If you purchased it online and saved it to your phone, you can show the digital version to a game warden, though having a printed backup is safer in case your phone dies or loses signal.
A game warden can stop you and ask to see your license at any time. If you cannot produce it, you may be cited for fishing without a license, which carries a fine and possible court appearance. The license must be in your possession — leaving it in your vehicle or at camp is not sufficient.
Seasons and Water-Specific Rules
Idaho's fishing seasons vary by species and by water body. Trout season generally runs year-round in most rivers and lakes, but some waters close during winter or have restricted seasons. Steelhead and salmon have specific seasons that vary by river system. Bass season typically opens in June. Before you fish, check the Idaho Department of Fish and Game website or call their office to confirm the season is open for the species and water you plan to fish.
Some waters have special regulations — catch-and-release only, artificial lures only, or single-hook restrictions. These rules are posted at boat launches and fishing access areas, and they are listed in the state fishing guide. Ignoring special regulations can result in a citation even if you have a valid license.
When a Three-Day License Makes Sense
A three-day license is the right choice if you are visiting Idaho for a short trip and want to fish for a few days. It is also practical if you live in Idaho but fish only occasionally — buying a three-day license for a weekend trip costs less than an annual license if you only fish a handful of times per year. Non-residents planning a week-long vacation should consider whether buying two three-day licenses (six days total) or an annual non-resident license is cheaper, depending on current pricing.
If you plan to fish more than six or seven days per year, an annual license usually costs less per day. If you fish only once or twice a year, the three-day license eliminates the waste of paying for a full year you won't use.
Frequently Asked Questions
Can I buy a three-day license and use it on non-consecutive days?
No. The three-day license is valid for three consecutive calendar days only. Once you purchase it, it becomes active immediately and expires at the end of the third day. You cannot pause it or use it on separate weeks.
Do I need a three-day license if I'm only fishing for catch-and-release?
Yes. Idaho requires a license for any fishing, whether you keep the fish or release them. Catch-and-release does not exempt you from the licensing requirement.
What happens if my three-day license expires while I'm still on a fishing trip?
You must stop fishing at the end of the third day. If you want to continue, you need to purchase another three-day license or an annual license before you fish again. Fishing without a valid license is a violation.
Can I buy a three-day license for someone else as a gift?
No. A license is issued to the person whose name and date of birth are on it. The person fishing must be the one whose name appears on the license. You can gift the money for a license, but the recipient must purchase it themselves with their own information.
Do I need a three-day license if I'm fishing on a guided trip?
Yes. The guide's license does not cover you. Every person fishing must have their own valid license, whether they are fishing alone or with a guide.
