Anglers flock to Yellowstone beginning the Saturday of Memorial Day weekend, when fishing season begins. By the time the season ends in November, thousands have found a favorite spot along the park's rivers and streams. Native cutthroat trout are one of the prize catches, but four other varieties -- brown, brook, lake, and rainbow -- along with grayling and mountain whitefish inhabit Yellowstone's waters. Popular sportfishing opportunities include the Gardner and Yellowstone rivers as well as Soda Butte Creek, but the top fishing area in the region is Madison River, known to fly-fishermen throughout the country.
Yellowstone fishing permits are required for people over age 16. Montana and Wyoming fishing permits are not valid in the park. Yellowstone fishing permits cost $15 for a three-day permit, $20 for a seven-day permit, or $35 for a season permit. Anglers ages 12 to 15 must have a nonfee permit or fish under direct supervision of an adult with a permit. Anglers younger than 12 don't need a permit but must be with an adult who knows the regulations. Permits are available at all ranger stations, visitor centers, and Yellowstone general stores.
