Known for its mysterious surrounding and astounding scenic beauty, Roopkund is a high altitude trek in Uttarakhand at the base of Trishul Peak and Nanda Ghunti. The maximum height of this trek is 5029 m. The trek in the Garhwal Himalayas offers magnificent views of the mountains surrounded by rock- strewn glaciers. This 9 days trek in Chamoli District is of moderate to difficult trekking grade. The lake at Roopkund is also known as a ‘mystery lake’ for the human skeletons and remains of horses that are found in huge numbers in the surrounding areas. These remains are believed to be of around the 15th to 16th century when a strong hailstorm took away the lives of hundreds of pilgrims. Lohajung is the base of Roopkund trek and is easily accessible by road from Rishikesh. The drive from Rishikesh to Loharjung is picturesque with the views of snow-clad mountains, sprawling valleys and meandering rivers. The trek to Roopkund starts from Lohajung and passes through the village of Didna. In between Loharjung and Didna, there is a small village called Kulling from where River Neel Ganga flows between Wan and Lohajung. From Kulling a steep ascent leads to Raun Bagad which is partly thick and dotted by the rhododendron, oak, and pine forest. On this trekking trail, the trekkers can spot many birds like fork-tailed Himalayan Magpie on the branches of rhododendrons. On the lower levels of Neel Ganga River, Lammergeiers are found soaring over the valley. One can also see yellow-throated marten.
