This fairly massive facility consists of a fortress tower, similar to the one in facility G06, however here the slide is in the form of a tunnel, creating the illusion that this is a secret tunnel used for escaping the fortress. The second tower is for younger children and access to it is easier: staircase with a railing and an asymmetrical ladder – net. For younger children, there is a separate slide and the access to the bigger tower from the smaller one is limited to them by a barrier, which the older kids go over in order to reach the bigger tower, after which they must go across a beam, that has a rope railing.
