The park has been a good option lately. Fish are rising to dries and large Cutthroat trout are hungry and willing to take a fly. Large attractors, stonefly dries, stimulators, ants, beetles have all been picking up fish. Nymphing a small dropper off one of these dries can be very effetive. Caddis nymphs, Yellow sallies, and PMD nymphs are all good bets. The West entrance has had the best dry fly action with the NE corner heating up now.
As always when in the Park, bring your bear spray and be respectful of the thermal features and the "no tread" zones. Read your regulations and know what's up.
