If your idea of a fantastic vacation means being by the water, make a beeline for Around the Hvaler Skerries. Whatever you choose to do here, you're unlikely to get bored of those lovely views.
Lots of visitors to Gamlebyen have this water-surrounded land mass on their schedule. But Around the Hvaler Skerries is just one of many places worth visiting in this area. If you've got time for more, Fredrikstad Museum will keep you amused.
