Malta Ski is part of Poznan's Lake Malta recreation zone, where the city has packed sports and family activities into a surprisingly compact area. The artificial slope is the headline, with skiing and tubing depending on season and conditions, but the broader appeal is having active options close to the centre.
It will not replace a mountain trip, and that is not the point. Use it as a playful break from churches, museums, and market squares, especially if you are travelling with children or want to see how locals use the Malta area on weekends.
