Fishing permits are required if you want to take advantage of Yellowstone's abundant lakes and streams. Live bait is not allowed, and for all native species of fish, a catch-and-release policy stands. Anglers 16 and older must purchase a $15 three-day permit, a $20 seven-day permit, or a $35 season permit. Those 12 to 15 need a free permit or must fish under direct supervision of an adult with a permit. Children 11 and under do not need a permit but must be supervised by an adult. Fishing permits are available at ranger stations, visitor centers, and Yellowstone General Stores.
All camping outside of designated campgrounds requires a free backcountry permit. Horseback riding also requires a free permit.
All boats, motorized or nonmotorized, including float tubes, require a permit. Boat permits for motorized vessels are available for $20 (annual) or $10 (seven days). Permits for nonmotorized vessels are $10 (annual) or $5 (seven days). Permits from Grand Teton National Park are valid in Yellowstone, but owners must register their vessel in Yellowstone.
