History of Bamsaru Khal Trek
The name Bamsaru derives from 'Bam Sarowar' which means lake on the left side. It is located slightly off-route near the khal (pass) and there are few lakes nearby; this might be the region that the pass has received this name. It connects two sacred rivers Bhagirathi (Ganga) and Yamuna. Locals believe that the nearby region of the pass was the place where Ganga and Yamuna once met before separating to flow through different valleys. Thus the Khal is seen as a symbolic confluence of these rivers' energies. Being a revered and spiritually significant place, many yogis and hermits have meditated here.
During the medieval time, the route around the Bamsaru Khal was part of the trans-Himalayan trade corridor which was mainly used by local communities. Locals from the Rawain region and Har-ki-Dun Valley used these trails for trade like salt, wool and grain between Yamuna and Bhagirathi valleys. These routes had great strategic and economic importance. The Rajput rulers and few tribal clans possessed control over these routes.
In the 19th and early 20th centuries, explorers and British surveyors started mapping the Himalayas. Bamsaru Khal was also mapped and noted in records for its high-altitude pass connecting the Harsil-Gangotri side to the Yamunotri region. Even after independence, the Bamsaru Khal region holds high strategic significance due to its proximity to the Indo-Tibetan border.
Highlights of the Bamsaru Khal Trek
Bamsaru Khal is a high-altitude pass which reaches an elevation of around 4,600 m. Due to its high-altitude and less-known status, trekkers don't come here often which has helped it remain untouched and pristine. It's a hidden gem that most trekkers are unaware of but once you see its natural beauty and picturesque surroundings, you won't want to leave from here.
Since it's surrounded by the majestic Himalayan peaks like Swargarohini and Bandarpunch, it forms like a natural amphitheatre. And when you see the reflection of these snow-clad peaks in the crystal-clear water of nearby lakes, it creates a breathtaking view. Especially during the sunrise and sunset, it looks more amazing. For photography lovers, this view is like a dream comes true.

Best time to visit the Bamsaru Khal Trek
The best time to do the Bamsaru Khal trek is from May to June and from September to mid-October. During this time, weather conditions are favourable for trekking and spending some time near the pass.
During this time, snow on lower altitudes starts melting but you can find it on higher altitudes. However, it’s more settled by this time and chances of avalanches are less. Temperature is relatively moderate: around 10°C to 15°C in day time and can be around 0°C to 5°C at night time; trekkers must stay updated on the weather forecasts. Sudden rainfall and hailstorms can happen, especially in the afternoon. Alpine flora is in full bloom during this time.
Post monsoon, weather is more reliable as rainfall subsides by early September. Sky is clearer and visibility of mountain peaks are best. Daytime temperature is around 8°C to 14°C and at nighttime, it usually drops below 0°C, depending on lower and higher altitudes. From October, weather conditions can turn cooler so it's advisable to complete the trekking before mid October.
Trekkers should avoid the monsoon season (July-August) due to heavy rainfall. It increases the risk of landslides and makes visibility very poor. Trails become slippery and leech-infested. Similarly, from mid-October to April is also not considered favourable due to cold temperature and heavy snowfall blocks the trails.
