Katori Sar Lake is a breathtaking high-altitude alpine lake located in the scenic Girgan Valley, also known as the Seven Lakes Valley, in the Pir Panjal Range of Jammu and Kashmir's Poonch district. Sitting at an elevation of approximately 3,810 metres (12,500 feet) above sea level, the lake is named after its distinctive bowl-shaped appearance, as "katori" means bowl in Hindi. Formed by ancient glacial activity, the lake is fed by crystal-clear snowmelt, creating a pristine setting surrounded by rugged peaks and alpine meadows.

Katori Sar is one of the interconnected alpine lakes of the Seven Lakes region, lying close to Bhagsar, Neelsar and Sukhsar Lakes. The trek to the lake passes through lush grasslands, vibrant wildflower meadows, pine forests, waterfalls and seasonal glaciers, making it one of the most rewarding trekking experiences in the Pir Panjal. The lake remains frozen for much of the year and is generally accessible between July and September, when the snow recedes and the surrounding landscape comes alive with greenery and colourful alpine flora.

Apart from its natural beauty, Katori Sar holds cultural and spiritual significance among local communities. Many believe that sages and saints once meditated near these serene alpine lakes, giving the area a peaceful and sacred atmosphere. The region also supports diverse Himalayan wildlife, including marmots, musk deer, Himalayan eagles and, on rare occasions, snow leopards. Due to its fragile ecosystem, visitors are encouraged to practise responsible tourism by preserving the lake's pristine environment and leaving no trace behind.
