If you're weary of noisy traffic and busy cities, pull on your boots and head out into nature. It'll be all around you when you walk along Olavsleden.
Olavsleden is a great place kick off your day in Halden. This trekking route comes recommended by fellow travelers, but it isn't the only thing to do here. Pencil in time for other attractions like Fredriksten Fortress, Vanninga, and Rød Herregård to make the most of what the area has to offer.
