Masar Tal Trek: Complete Route Guide Near Kedartal and Gangotri

Introduction to Masar Tal

Masar Tal is a stunning, lesser-known alpine lake in the Gangotri region of Uttarakhand, sitting at approximately 4,700 metres, close to the more famous Kedartal. While the classic Kedartal trek draws the majority of visitors to this part of the Gangotri National Park, Masar Tal remains a quieter, equally spectacular alternative, often visited as an extension or variation of the Kedartal route for trekkers seeking a less crowded high-altitude lake experience. Framed by the jagged Thalay Sagar (6,904m) and Bhrigupanth (6,772m) peaks, Masar Tal offers some of the most dramatic mountain reflections in the Garhwal Himalayas.

Trek Overview and Key Statistics

The Masar Tal trek starts from Gangotri (3,100m), the same trailhead used for Kedartal and for pilgrims visiting the Gangotri Temple, covered in detail in our Gangotri temple travel guide. The round trip covers approximately 26-28 kilometres and is typically completed in 5 days including acclimatization, with a maximum altitude of around 4,700m at the lake itself. The trail difficulty is graded moderate to challenging, owing to a steep, boulder-strewn ascent in the final stretch and the high-altitude exposure above 4,000m for two consecutive days.

Day 1: Gangotri to Bhoj Kharak

The trek begins at Gangotri town, where trekkers register at the forest checkpost before entering Gangotri National Park. The trail climbs steadily through dense birch and rhododendron forest along the true left bank of the Kedar Ganga stream, gaining roughly 800 metres over 7 kilometres to reach the meadow campsite of Bhoj Kharak (3,800m). This section is relentlessly uphill with few flat stretches, making it one of the toughest single days of the trek despite its modest distance. Camping at Bhoj Kharak offers the first proper views back toward the Gangotri range.

Day 2: Bhoj Kharak to Kedar Kharak

Day 2 is comparatively gentler, covering about 4 kilometres and gaining 400 metres to reach Kedar Kharak (4,200m), a wide alpine meadow used as the base camp for both Kedartal and Masar Tal. The short distance is deliberately built into the itinerary to aid acclimatization before the push above 4,500m. Kedar Kharak offers open views of Thalay Sagar's sheer granite face and is a good spot for an afternoon acclimatization walk toward the ridge above camp.

Day 3: Kedar Kharak to Masar Tal and Back

This is the trek's defining day. From Kedar Kharak, the trail to Masar Tal diverges from the standard Kedartal route, climbing over a rocky moraine ridge and traversing a boulder field for roughly 5 kilometres one-way, gaining nearly 500 metres. The final approach involves scrambling over large, unstable boulders, and trekking poles alone are often insufficient — careful hand-and-foot navigation is required in several sections. Reaching the lake rewards trekkers with an almost perfectly still turquoise-blue alpine lake mirroring Thalay Sagar's near-vertical north face, a view many consider even more dramatic than Kedartal itself due to the closer, more direct sightline to the peak. Most groups spend 1-2 hours at the lake before retracing the route back to Kedar Kharak the same day.

Day 4-5: Descent to Gangotri

The final two days retrace the ascent route, descending from Kedar Kharak through Bhoj Kharak back to Gangotri. Many trekkers choose to combine this descent into a single long day (11 kilometres, mostly downhill) if time is limited, though splitting it over two days is gentler on the knees given the steep gradient. From Gangotri, the road journey back to Uttarkashi and onward to Rishikesh or Dehradun takes roughly 7-9 hours by shared or private vehicle.

Masar Tal vs Kedartal: How They Differ

Both lakes share the same approach trail up to Kedar Kharak, which is why most operators offer Masar Tal as an add-on rather than a standalone trek. Kedartal itself sits slightly higher at around 4,750m and is reached via a more established, cairned trail, while Masar Tal's final approach is rockier and less frequented, giving it a wilder, more untouched feel. Trekkers with sufficient time and acclimatization sometimes visit both lakes on the same extended itinerary, spending an additional day at Kedar Kharak to do so — a combination increasingly popular among trekkers who have already done standard routes like Kedarkantha and are looking for a more offbeat Garhwal experience.

Best Time to Trek Masar Tal

The trekking season runs from mid-May to mid-October, mirroring the Kedartal season, with a monsoon gap in July-August when landslide risk on the Gangotri approach road increases significantly. Late May and June offer the best combination of stable weather and manageable snow at the lake, while September and early October bring the clearest skies and the most dramatic autumn light on Thalay Sagar, at the cost of colder nights (regularly below -10°C at Kedar Kharak).

Permits and Practical Information

Since the route lies within Gangotri National Park, an Inner Line Permit and forest entry fee are mandatory, arranged at the Uttarkashi Forest Department office or through your trekking operator in advance. A local guide is compulsory for this route given its remote, poorly marked final stretch to the lake, unlike the more established main Kedartal trail. Basic mobile network is available only in Gangotri town; beyond Bhoj Kharak, there is no connectivity, so carrying a physical map or GPS device and informing someone of your itinerary beforehand is strongly advised.

What to Pack

Given the boulder-hopping nature of the final approach, sturdy ankle-support trekking boots with good grip are essential — more important here than on smoother trails. A 4-season sleeping bag rated to at least -10°C, trekking poles, gloves, a warm down jacket, and UV-protective sunglasses round out the core kit. Given the remote and rocky terrain, a basic first-aid kit with knee and ankle supports is worth carrying, since minor slips on the moraine section are the most common trail injury.

Conclusion

Masar Tal offers one of the most rewarding payoffs in the Gangotri region for trekkers willing to handle a rugged boulder approach: an intimate, mirror-still lake beneath one of Garhwal's most iconic granite spires. Whether visited alone or combined with Kedartal on an extended itinerary, it remains one of Uttarakhand's best-kept high-altitude secrets, and a natural next step for trekkers who have built up experience on established routes like Har Ki Dun or the main Kedartal trail.
