Follow the Lederhosen

Unless you’re celebrating at the actual Alps, the view from the Watermark Bar on South Street is hard to beat. The pier stretches out into the East River, with the Brooklyn Bridge providing an Instagram-worthy backdrop for photos with roller-skating beer maids and 1-liter glass steins. The vibe here is frat party meets beer hall: The speakers pump pop music, and the pier is packed with games, including pingpong, cornhole and an oversized beer pong played with volleyballs and trash cans. You can soak up some of that German beer with giant pretzels, brats and more.

Andrew Freerks, 35, celebrates Oktoberfest every year along with his father, sister and brother-in-law. It may not be as authentic as the fests they’ve attended in Germany, but it’s still a heck of a party.

“This is like New York takes over Oktoberfest,” he tells The Post.

“Watermark presents OktoberFest,” Saturdays and Sundays, 11 a.m. to midnight, through Oct. 20. 78 South St., at Pier 15
