The short version: three of the most asked questions, answered in a line each. The rest of the page goes into detail.
- How hard is the Ponker Lake trek? It is graded moderate, with steep, rough trails and long days, and no technical climbing.
- How cold does it get at Bimthang? It gets cold at night, so pack a warm layer for Bimthang, along with a waterproof jacket.
- What is the weather like on the lake day? Mornings are usually clearer, while cloud and wind often build later.
Is the altitude gain on the Ponker Lake trek quick?
Yes. Going from about 2,500 m at Gho to about 3,600 m at Bimthang in a day, then to about 4,100 m the next day, is quick. Add a night at Bimthang if you can, and drink plenty of water.
What symptoms should make me turn back before the lake?
A worsening headache or nausea. Bimthang and the lake are well above 3,500 m, so take these seriously. Tell your guide early, rest, drink plenty of water, and descend if you do not improve. The lake is not worth risking altitude illness.
How hard is the Ponker Lake trek?
It is graded moderate, with steep, rough trails and long days, and no technical climbing. The trail climbs steeply from Gho to Bimthang and again above Bimthang, and the lake day is long, so strong legs and good lungs help.
How cold does it get at Bimthang?
It gets cold at night, so pack a warm layer for Bimthang, along with a waterproof jacket. Winter is very cold near the lake. Ask your agency what bedding is provided and exactly where you will sleep, since reports differ on lodges versus camping higher up.
What is the weather like on the lake day?
Mornings are usually clearer, while cloud and wind often build later. The trail can be muddy or snowy depending on the season. Start early to improve your chance of views and to finish in daylight.
How should I prepare my legs for the steep days?
Train with hill walks and stairs while carrying a daypack, ideally for a couple of months before you go. Trekking poles take pressure off your knees on the descent, and boots should be broken in before arrival. Strong legs and good lungs make the steep sections far easier.
