Best Time to Climb Island Peak
During Spring season between March and May the weather be stable, the view is clear and beautiful. The day during this time and longer and warmer. Also, during this season, many people visit the Island Peak and is more crowded as compare to any other season.
During Autumn season between the month of September and October the area is less crowded as compared to Spring season. But the days are a bit shorter than spring and is slightly colder. But the main problem during this time is, the weather won’t be that open. But still, this is the season to summit Island Peak.
