The Hidden Lake is a subterranean lake in Club Penguin Rewritten. It opens out to the sea, and a variety of sunken treasure drifts here from underwater. Waterfalls flow here into the sea from underground reservoirs.

An underwater door here leads to the Underwater, but the door can only be opened with the Moss Key Pin.
