Pangong Tso, A beautiful high altitude lake at 4350 meters with deep blue waters, surrounded by tall mountain peaks. This lake lies on the Indo - China boundary, with only one fourth of the lake being in India. The road to this lake passes through Chang-la pass, claimed to be at 5425 meters. It's a five hour drive (149 Kms) from Leh to this place. There is also a small camp on the way where a Yak Safari can be done. The passage is also very tough to cross by car. So a four-wheel drive car is recommended. Experienced bikers should not have any problem. Day return trips from Leh avoid the AMS issue, but you won't be able to see much during the your 60 minutes stay there. Overnight trips directly from Leh is outside safety guidelines. The safe and comfortable option is to plan this trip at the end of your stay in Leh , and with a overnight stop at Tangtse (altitude 3950) .
