The Fiskidagurinn Mikli takes place on the second weekend of August and is the most unusual free meal in Iceland. The fishing boats land their catch, volunteers man the grills, and the food is served without charge from morning to evening. It is genuinely a community act of hospitality rather than a tourist promotion.
If you are in northern Iceland in early to mid-August, planning around this festival is worth the effort. The town fills up and the atmosphere is relaxed and celebratory. Check the exact date each year as it shifts slightly. Dalvík harbor and town centre.
