Length: 7.9 mi • Est. 5 h 46 m
Lovely trail up the Watkin path recommended to anyone with reasonable level of fitness and adequate clothing. The views are amazing ! The clear blue lagoons with waterfalls, the wildlife and the landscape will take your breath away. This is a true adventure but pay attention, the trail is a steady ascent and near the top it becomes steeper and requires some scrambling over loose rock. Nothing too difficult in dry weather but not recommended for beginners and could become dangerous in wet weather. Relatively quiet path compared to the more popular routes, although the summit itself was still very busy. Definitely recommended for an alternative route up or down the mountain! Show more
