Kobonilagala is a 1556m height mountain situated near Thangappuwa village. This mountain is known as Aliya Kanda by the villagers as per the exact shape of the elephant. There are 2 routes to reach the mountain such as from two opposite side of the mountain. We followed the hardest one getting upward from the Thangappuwa to Corbet gap footpath side. But the easiest path is fallen from the Silent Bungalow side located near Liyanagahapala Estate.
