About Big Fishing Creek

Pennsylvania's northernmost classic limestone stream, flowing through the Bear Meadows / Loganton area in Clinton County. Class A wild brown trout, a strong Sulphur hatch through May and June, and a Green Drake emergence that mirrors Penns Creek. Less crowded than the marquee Centre County water, with several catch-and-release sections.
