The best time to go to Eidfjord is during the summer months, from June to August, when the weather is mild and all attractions are fully accessible.
During this period, you'll experience long daylight hours, sometimes up to 18 hours, which provides ample time for exploring. Temperatures typically range from 15°C to 20°C (59°F to 68°F), making it comfortable for outdoor activities like hiking, cycling, and boat tours on the fjord. This is also when the famous Vøringsfossen waterfall is at its most impressive due to increased snowmelt.
For travelers who enjoy outdoor adventures, this season is ideal. All hiking trails, including those around Hardangervidda National Park and the Simadalen valley, are open and well-maintained. Boat excursions on the Eidfjord, offering views of the surrounding mountains and waterfalls, operate frequently.
If you prefer fewer crowds and don't mind slightly cooler temperatures, late spring (May) or early autumn (September) can also be good options. Many attractions remain open, and the landscape is particularly scenic with blooming flowers in spring or vibrant fall foliage.
