Yellow Breeches Creek is a world-renowned limestone-influenced trout stream located in south-central Pennsylvania. Originating on South Mountain in Michaux State Forest, this picturesque waterway flows approximately 49 miles through Cumberland Valley before joining the Susquehanna River near New Cumberland. The creek is characterized by its low gradient, long riffles, and smooth flowing pools, creating ideal habitat for various trout species. While primarily a freestone stream, Yellow Breeches benefits significantly from limestone spring water inputs that provide an excellent pH level, supporting a diverse aquatic insect population and maintaining relatively consistent water temperatures. Designated as a Pennsylvania Scenic River in 1992, the creek offers anglers a serene fishing experience in beautiful surroundings while providing some of the best trout fishing opportunities in the eastern United States.
