When the temperatures start rising, there is only one thing to do in Helsinki - head to the best rooftop bar or summer nightclub in town and cool down with a refreshing drink or two. Some of these venues are open all year round, whereas others turn into summery party destinations during the warmer months, both offering spectacular city views as far as the eye can see. So, why not stimulate your senses with an exciting blend of good drinks, great music and epic views of the city?
