The Warfaaz Lake (surface area 6.5 hectares), at the gates of the city of Spa, is fed by the Wayai. This river springs in the hamlet of the same name; it flows through the town of Spa, and then, at Theux, in the Hoegne. The lake is popular with fishermen and there are many pathways along the shores. Several restaurants are located nearby. There is also a large playground for children.
