As the snows melt, colour and life return once again to the National Park.
During the month of May there can still be heavy falls of snow within the National Park, and it is not unusual for large avalanches to descend.
By the end of May trails in the lower and sunnier parts of the Park become accessible. Trails in the higher areas remain under snow, and are generally only passable towards the end of June. This is a quiet time of year, and a good moment for observing the Park’s wild life. The birds in particular are especially active at this time of year.
