Within Glacier there's an almost unlimited range of fishing possibilities, with catch-and-release encouraged. You can fish in most waters of the park, but the best fishing is generally in the least accessible spots. A license is not required inside the park, but you must stop by a park office to pick up a copy of the regulations. The season runs from the third Saturday in May through November. Several companies offer guided fishing trips. Fishing on both the North Fork and the Middle Fork of the Flathead River requires a Montana conservation license ($10), an AIS Prevention Pass ($15), and a Montana fishing license ($25 for two consecutive days or $86 for a season). They are available at most convenience stores, sports shops, and from the Montana Department of Fish, Wildlife, and Parks (406/752–5501
