One of Warsaw's most legendary riverside beach clubs, when the city tried to put the clamps on this cult party place it simply moved across the river, reopening as part of the epic Lunapark adult wonderland complex. Now it functions as the beating heart of the capital's most popular summertime party place. While hipsters can play games, admire art, eat street food and wander around the woods and sand of Lunapark's long stretch of riverside, it's Hocki Klocki where they pack together to get absolutely plastered and dance their asses off under the stars. Although it's little more than a colourful pop-up bar in the woods with a roof deck and large dancefloor - or perhaps because of it - this place is a lot of fun, drawing some great DJs and weirdo bands. Try not to get sick sucking down their 'infuzje' - booze blended with various Polish candies. Friday to Sunday only, this seasonal party pops off from early May until about the end of September (depending on the weather).
