Have a blast this summer at Kensington Metropark's Splash-N-Blast, containing two, 240-foot twisted waterslides and an adjacent spray area. Slide down the open slide or ride down in the dark through the enclosed slide. Have a blast in the spray area as water shoots from cannons, palm trees, serpents and a whale. The Splash-N-Blast is located on the north end of Martindale Beach in Kensington Metropark and is open daily from 11 to 7 through late summer. A vehicle entry permit is required to enter Kensington Metropark.
