Vlietland is a 300-hectare recreational area situated in the heart of the Randstad, beside the A4 motorway between Leiden and The Hague.

Its centerpiece is a group of three lakes totaling 130 hectares, formed by sand extraction that took place from 1968 to 2001.

The area is now one of the largest and most popular recreation zones in the Netherlands, drawing paddlers, sailors, rowers, and swimmers to its waters.

The Zuidgaag access point puts paddlers directly within reach of the waterways that connect Vlietland to the broader network of the Hollandse Plassen and the Green Heart.

On land, the area offers walking, cycling, and horse-riding trails linking it to historic towns including Leiden, Voorschoten, Leidschendam, and Delft.

Water-sport rentals, a sailing school, and a campsite are among the facilities found within the recreation area.
