Portageville is a hamlet located in the town of Genesee Falls in Wyoming County, New York, United States.

They had to portage several miles to the site of present-day Mount Morris, where they could embark for the rest of the journey downriver.

The Genesee River Gorge with its scenic waterfalls was formed after the original valley was buried in glacial debris from the last ice age and the river had to cut a new valley though the Devonian sedimentary rock of the area.

The site has now been designated Letchworth State Park and is a major tourist attraction, with the lower entrance at Portage.

It is a Greek Revival style structure with Gothic and Federal elements dating to 1841.
