Iceland offers a diverse and challenging climate for hikers. Winter months (October to April) often have severe weather, making most trails inaccessible. The spring (May to June) presents more daylight hours but unpredictable weather conditions.
Summer (July to September) is the best time for hiking with long daylight hours, mild temperatures, and stunning, blooming landscapes. However, weather can still be capricious, so preparation is key.
Hiking off-season is not recommended unless you are highly experienced and equipped. Check weather forecasts on
