evidence: Nelong Valley, located within Gangotri National Park in Uttarkashi, Uttarakhand, is a high-altitude river valley resembling the landscapes of Lahul, Ladakh, and Tibet. Due to this resemblance, the valley is known as the "Ladakh of Uttarakhand." The valley shares its border with the Kinnaur district of Himachal and Tibet. [...] Nelong Valley is located within Gangotri National Park, so the opening and closing times of the National Park also apply to the valley. The National Park opens in April, and tourist visits are allowed only after forest officials complete their reconnaissance. In April, the National Park is still covered with snow, as is Nelong Valley. The best time to visit the nelong valley is from May to June and mid-September to mid-October. [...] Before the Sino-Indian War of 1962, Nelong and other villages were residences of the Jadh Bhotiya tribe. The Jadh of Kinnaur and Nelong had trade ties with Tibet, and people from here used to go to Tibet regularly for trade. However, due to the war, all the villages were evacuated by 1965, and the Jad community was settled in Bagori and Dunda.
