Another 13 kilometres from Nakeela La, and you reach Lachlung La. Here you get your first experience of 5000 metres plus air. Lachlung La is 5100 metres above sea level. The scene, you will realise, has now become more sandy, and the rocky land is starting to decrease. The bigger formations are also made of sand and not of rocks. The air is thin, mind you, so don't jump and run around in excitement, or for photos, as within seconds, breathlessness gets the better of you.
