Pangong Tso, a high-altitude endorheic lake in the Himalayas, is renowned for its stunning blue waters that change shades with the sunlight. Situated at approximately 4,350 m (14,270 ft), it requires acclimatization to avoid altitude sickness. Accessibility can be a challenge due to the remote location and rugged terrain, and a special permit is required to visit. Guided tours are highly recommended, especially for first-timers, to manage permits, transportation, and altitude concerns. The best time to visit is from May to September, as the lake freezes in winter, restricting access. Expect costs to be relatively high due to transportation and permit fees, and plan for at least a day trip to fully experience the lake. Travelers should note the delicate ecosystem and adhere to responsible tourism practices.
