Arethusa Cirque Meadow
Past travellers have left rave reviews for the spectacular meadow at the union of the trail and the creek where the trees open up. If you are visiting during fall months, then you might feel dumbfounded to see the raw beauty of the larches’ warm golden glow. The trail forks from this point and loops around the cirque. You can either go clockwise or anticlockwise. The former is perfect for those who wish to go uphill and the latter is easier as the path is more of a descent.
