Twentymile Creek near North East PA

If you’re into fly fishing, you’ve likely heard of the great steelhead found in Pennsylvania and throughout the Great Lakes region. There are many adventures to be had and this area is ripe with guides to assist you along the way. What if you don’t want a guide, though?

Whether you’re looking to plan a fly fishing excursion on a budget or you just want the privacy of doing the trip alone, that’s always an option. This guide will help you learn all about Twenty Mile Creek so that you can create the perfect adventure, no matter what you have in mind.

About 20 Mile Creek

Fly fishing for steelhead on Twentymile Creek in Pennsylvania

Twenty Mile Creek is the largest of the eastern creeks and one of the most popular in the miles of creeks offered in the Pennsylvania portion of Steelhead Alley. The creek averages 20 to 30 feet in width in the lower reaches and is characterized by a mix of boulders, slate, broken shale and gravel. It starts almost due north of Exit 45 on I-90 and passes through the picturesque grape-growing region that North East Township is known for.

The unique thing about Twenty Mile Creek is that most of the fishing access is on private property and by permission of the property owners. They are generally more than willing to be accommodating, but you should be mindful to be courteous and ask. Fly fishing in this creek offers plenty of opportunities throughout, so long as you have permission.

You’ll find great steelhead fishing in this creek, along with brown trout and the occasional warm water straggler. The creek runs low in some areas and high in others, so it’s important to check water levels before you hit the stream so that you don’t find yourself fishing in a puddle.

The steelhead here are a bit smaller than average, but there are plenty of them. As with most of the creeks in the region, the best catches will come as the water levels rise, with fall to spring being the most popular time for landing the best catch. Only the last four miles of this creek are located in Pennsylvania, so make sure that you’re paying attention to where you’re at as fishing regulations might vary in New York.

Because this creek is stocked, most anglers will do well with simple flies. The fish aren’t as picky early in the season, but you might have to get creative later on. Whether you’re working your way up to it or starting with the best, Twenty Mile Creek is a great choice.

Best Places to Fish Twentymile Creek

There is no vehicle access at the mouth of the creek, which is found just about a mile west of the state border with New York. You will find vehicle access along Route 5, where you can park near the bridge and find a path down to the creek. Access is only available on the west bank here. 

There is a wider, slow-moving area at the mouth, and upstream from there, you’ll find a section of runs and riffles with pools that have good holding water. If you keep heading upstream, you’ll find a sizable pool just below the waterfall and the iron bridge. Unfortunately, this is mostly private property and you may not be able to fish here. 

At the intersection of Middle Road and Hirtzel Road, you’ll find a path leading to Twenty Mile Creek, and right north of the freeway, you’ll find Hirtzel Pond, which is also stocked with trout. Limited parking is available here. Stinson Road at Gay Road offers another access point, with posted signs for parking and walk-in fishing. 

Gulf Road, located just south of Route 20 near the railroad underpass, is a good access point because it’s close to a pool, and this is where you’ll find the “snake hole” that was once a popular spot.

Best Time to Fish Twentymile Creek

As with all trout fishing in the New York and Pennsylvania region, the season runs from early fall until late spring, with steelhead showing up during September at the mouth and growing in number into October. By late October, the creek will be ripe with fish in many areas. 

Steelhead remain plentiful until the end of April, and perhaps even into May during cooler years. However, in the summer months, the water is too warm and the levels are much too low to find any fish. The best time to plan a trip here is between October and April, although January and February might prove to present their own challenges. 

Follow the hatches in the spring for the best fishing, including midges and caddisflies. Aquatic insects can be a good indicator of whether you might find good fishing in a particular area during the spring months, so take that into account. 

If you go during the fall and spring when the season is in full swing, you’ll often find crowds at many of the best locations. Prepare for that, or try to plan to go at a slower time to avoid it.
