Hersheypark, in Hershey, Pennsylvania, has unveiled its US$17.6m (£11m, 12.6 euro) expansion.

The project comprised the expansion of the park's Boardwalk area, which opened in 2007, and is called The Boardwalk: The SEAquel.

The work included the installation of The Shore, a 378,000-gallon wave pool and the Intercoastal Waterway, a 1,360ft lazy river.

The area also features a changing area, lockers and a restaurant, as well as 27 cabanas that can be rented out.

The new attractions have replaced the former Canyon River Rapids, which were in place from 1987 until last August.
