An infinity pool is a type of swimming pool with a design that appears to have no boundary, as the water's edge extends to the horizon. This effect is achieved by having the pool's edge positioned at the same level as the surrounding landscape or building, creating the illusion of water merging with the environment. High-altitude infinity pools are located at significant elevations and offer a unique vantage point, often with stunning views. They are typically found in luxury resorts or high-end private homes.
