Mu Gompa is the highest and most remote monastery in Tsum Valley, at about 3,700 m near the Tibetan border. It is the highest point on the usual route, reached as a side trip on day 8 from the Nile and Chhule area, and then you walk back down.
Altitude: about 3,700 m. Heights quoted for villages and camps vary by source, so treat this as a guide.
Where Mu Gompa is and why trekkers stop
Mu Gompa lies at the northern end of the valley, beyond Nile and Chhule, close to the Tibetan border. The route climbs gradually through the upper valley, passing Rachen Gompa, a nunnery, along the way on many itineraries.
Trekkers come for the sense of arriving at the far end of a quiet valley. The full Tsum plan with Mu Gompa takes seven to eight days from Lokpa, and it is the destination that makes the longer version worth doing.
What to expect at Mu Gompa
Expect a setting that feels spare and remote: stone buildings, prayer flags, long mani walls and wide high slopes, with the borderlands beyond. Visits to the gompa should be quiet and respectful, so ask before taking photographs inside and follow your guide's lead.
The cave linked with Milarepa is among the sites often mentioned in this part of the valley, though details depend on the day and your guide. Most groups walk up and back in one day from their base lower down, then continue the descent.
Altitude and how you may feel
At about 3,700 m this is the highest point on the usual route, and the valley rises from about 2,240 m at Lokpa, so the total gain is substantial. Mild altitude symptoms such as headache, fatigue and disturbed sleep are common.
Go slowly, keep warm and drink plenty of fluid. Altitude illness can strike even fit walkers. If symptoms get worse, turn back and descend, because lower ground is the best treatment. Spending the day as a round trip from a lower base also keeps the sleeping altitude manageable.
Lodging, food and practical tips
Facilities near the monastery are very limited, and many groups return to a lower village to sleep. Carry water, snacks, a warm layer and a windproof jacket, because weather can turn cold and windy even in good seasons.
Tsum Valley requires a restricted-area permit and a licensed guide through a registered agency. Dress modestly, walk clockwise around prayer walls as your guide advises, and never touch religious objects without being invited. A little cash for a small donation is appreciated.
