Swimming is allowed in the largest of the three Daun maars. Just how huge the lake is becomes clear when you look at it from above: its surface area is equivalent to 21 soccer fields. After a hike you can dive into the water. During a boat trip you can relax with a view of the sparkling blue, let your thoughts run free and recharge your batteries for new tasks. Free Wi-Fi is also available in the area of the Maarbad!
