About Raet National Park

Raet National Park is a coastal national park in Agder county in southern Norway that protects a stretch of shoreline, islands and shallow sea areas along the Skagerrak. The park safeguards a moraine ridge and associated coastal habitats formed by glacial action.

The protected area includes rocky skerries, shallow bays, beaches and stretches of shoreline used for recreation, birdwatching and low-intensity boating. Trails and coastal access points allow visitors to explore exposed shoreline and island habitats.

The park was designated to protect coastal landforms and marine areas and is managed under Norway’s national park framework. Its boundary runs along the Agder coast, encompassing nearshore waters and archipelagos.

Raet National Park is located along the southern Norwegian coast in Agder, neighboring coastal towns and villages and accessible from regional roads serving the Arendal-Tvedestrand area.

  • Geology and ecology: Protects a coastal moraine ridge and many small islands and skerries left by the last ice age, important for coastal ecology and birdlife.

Getting There & Around

How to Get to Raet National Park

Raet National Park stretches along the coast of Agder and has multiple access points near towns such as Arendal and Tvedestrand. The park is most easily reached by car from Arendal - local roads lead to beaches and trailheads with roadside parking a short walk from the shore. If coming from farther away use the E18 highway to the Arendal area and then follow local county roads to the specific coastal access you want; regional buses connect Arendal with nearby villages where you can start your walk into the park.

Tips for Visiting Raet National Park

  • Plan visits in late spring and summer when sea conditions, light and access to skerries and islands are most reliable and daylight is long-many landing spots are only practical in the warmer months.
  • Use marked landing sites and local boat operators for island access and check tide and weather forecasts first; the park contains many low, rocky islets that are best approached at calm sea state.
  • Bring binoculars and spend time on the less-visited skerries-birdlife and coastal geology are highlights that many visitors miss when they stick to the main shoreline trails.
