Among the high-quality treks in the Garhwal Himalayas is the hike to the exquisitely beautiful&mdashand slightly sinister&mdashRoopkund. This famous lake, with its human skeletal remains, is frozen most of the year. The Great Indian Outdoors team makes it accessible for four months every year, with their spring/summer hikes ending in late June and a two-month window opening again in September. Over six days, trek through the stunning Ali and Bedni bugyals, see up-close views of giant peaks like the Trishul and Nanda Ghunti, hit the final, hard and ultimately rewarding push past Bhagubasa, and unwind at the picturesque mountain village of Wan on your way back. Accommodation in Barsu is basic and clean, all meals are nutritionally planned, and camping arrangements focus on safety, quality and comfort (Rs 11,550 per person gio.in/trek-to-roopkund).
