The extended daylight hours, with the sun often staying up until late in the evening, provide ample time to explore the Heidal valley and its surroundings. Many local attractions, such as the historic Heidal Church and the various craft shops, operate on extended hours during the summer.Summer is particularly well-suited for families and outdoor enthusiasts. The warmer weather allows for hiking and cycling along the many trails in the area, including paths that wind through the traditional farmsteads and along the Sjoa River. River rafting on the Sjoa is also a popular activity during these months when water levels are generally good.While summer offers the most accessible and activity-rich experience, the shoulder seasons of May and September can also be pleasant for travelers looking for a quieter visit with fewer crowds.
