The pool that merges with the horizon
The infinity pool — also called an overflow or horizon pool — is the pool without a visible edge: on at least one side the water level lies exactly at the height of the pool edge, so that the water seems to flow over the edge and merge with the landscape behind it. Photographed in front of a mountain panorama, a lake or a valley, it has become the emblem of the modern wellness holiday — the picture everyone knows.
How the illusion works
Behind the edgeless effect is simple technology: water flows constantly over the overflow edge into a lower catchment channel, from which it is pumped back into the pool. The water level thus stays at edge height to the millimetre — and the eye finds no boundary between pool and view. The more dramatic the setting behind it, the stronger the effect; the infinity pool is architecture that frames the landscape.
Indoors, outdoors, heated
The infinity pool unfolds its greatest appeal outdoors with a view — and heated all year it becomes a winter experience: lying in warm water while snow or frost stands all around. Some houses run indoor infinity pools with a floor-to-ceiling window front, others combine indoor and outdoor pools. The Waldhaus Ohlenbach in the Sauerland, for instance, opens its pool with a panoramic view of the forest; mountain resorts stage it as a rooftop or hillside-edge pool.
More than a beautiful picture
The infinity pool is a marketing icon and a real experience at once — the combination of warm water, weightless calm and a wide view is demonstrably relaxing, entirely without esotericism. For many this very image is the reason for the trip: a pool that releases the view instead of bounding it with tiles. When choosing a hotel a second look at the photo is worth it — at what lies behind the edge.
