DIY Guide to Fly Fishing Lycoming Creek in North-Central Pennsylvania

North-Central Pennsylvania has plenty of excellent freestone trout streams, so what makes Lycoming Creek so special?

Well for one thing, the creek is one of the most heavily stocked streams in the area.

But it might just be its breathtaking scenery that will make you fall in love with Lycoming Creek.  

Bordered by thick overhangs of beautiful oak, buttonwood, cherry, and beech trees, Lycoming Creek might just be the most picturesque option for fly fishing in Pennsylvania.

Lycoming Creek is roughly 37.5 miles long and is a tributary of the West Branch Susquehanna River. Its river source is in Tioga County. The center of Lycoming Creek, located around Grays Run, is a heavily wooded area of Tiadaghton State Forest. There is a 1.4 mile delayed-harvest area from the county line downstream, finishing at Sandy Bottom.

The area from Cogan Station to the confluence of Roaring Branch is heavily stocked through late spring. You’ll most likely find brown trout and brook trout, but you might see some rainbow trout as well.

Some of the smaller streams, some of which are Class wild trout streams, that feed Lycoming Creek include Pleasant Stream, Grays Run, Roaring Branch, Hoagland Run, and Trout Run.

Fly fishermen can expect good riffles and pool water in Lycoming Creek. Because of its thick overhang, the water stays generally cool throughout the year.

Trip Planning Tips

However, you could also utilize any of Northern Pennsylvania’s major or municipal airports, if you don’t mind a couple hours of scenic driving to reach your destination.

Because of its proximity to Williamsport Regional Airport, there are many lodging choices around Lycoming Creek. Econo Lodge is only a twenty minute drive from Lycoming County, and offers on site dining and free Wi Fi. The Budget Inn is a little bit closer to Lycoming Creek, and has complimentary breakfasts.

If you are looking for a campground, it is hard to beat Haleeka Campground, both in terms of convenience (it’s a mere thirteen minute drive to get to the Creek) and flourishing wildlife. Sheshequin Campground is another nearby option, but it can get pretty packed during peak season, so if you’re looking to avoid the crowds, you might want to hold off on visiting in the spring.
