tl;dr – A new project will see the park’s footprint grow significantly.
This spring, Niagara Falls State Park – the oldest state park in the United States – will add more than 150 acres, as two neighboring state parks will join the park’s boundaries.

According to Smithsonian Magazine, Whirlpool State Park and Devil’s Hole State Park will soon become zones within Niagara Falls State Park.

An additional “two miles of new trails” will join the Niagara Falls State Park mapping, and – according to Derek Heid, reporter from WKBW – once the “project is complete, Niagara Falls State Park will feature nearly five miles of continuous shoreline along the Niagara River, from the Niagara Scenic Parkway to the Niagara Power Vista Visitor’s Center.”
