Salzburg can get scorching hot in the summer months. What better way to cool off than by going for a dip outside? The Salzach River, though cool and enticing, is off-limits to bathers because of the strong currents, but Salzburg boasts three central outdoor swimming pools, including one adventure pool in Leopoldskron. If you have a free afternoon, kick back poolside while enjoying the mountainous location. Most pools also have a volleyball court and café, so why not make an afternoon of it? You can also travel to the nearby lakeside town of Fuschlsee.
