Is it an urban oasis, a cultural free spot, an urban beach? In any case, you can sit outside here in kind of an alternative atmosphere (that belongs to the Oostenburgereiland), and have a drink.
Near the water side is the beach like part, covered with sand.
There is also an evening programme, with music and other performances.
Reach the Oostenburgereiland are by going to the end of Czaar Peterstraat, then to the left.
