An ethereal walk traversing countries and geographies, from Indian desert mounds-of-sand like mountains of  Spiti Valley to the vast expansive high altitude  plateau, Changthang - the home of the nomadic Changpa’s in Tibet, is the Parang la trek. The trek reaches it crescendo, not just on one day – the day we cross the Parang la across the ragged mountains, but another – the day we soak in the serenity of the Tso Moriri. The trek is an endless walk along through green meadows where the Kiangs (Tibetan wild horses) run wild, through little bushes of green in the arid brown of the Spiti that are the rhododendrons, along the cobalt blue stillness of the Tso Moriri and then on to the  vast expansive ill-populated wetlands of the Changthang plateau. This trek embodies the art of mindfulness – Vipaasana Meditation – One is truly mindful of their surrounding, their breath and the breathtaking visages. The trip starts with a drive across the stunning landscapes and the lush green meadows of the Kullu valley to the arid mountain scapes of Lahaul and Spiti.  To get acclimatised to the high altitude, the next couple of days is well spent understanding the ways of the monks and the people of Spiti in the millennial old, favourites of Dalai Lama -Toba and Kye/Key monasteries, soaking up some good energy and history. Taking the traditional trade route between Ladakh and Spiti, we cross Parang la (5580m), source of the Pare Chu River that flows from India to Tibet and final circles back to India to join the Spiti River.  Then we descends to the almost never-ending plateau of  Changthang and walk to the Tso Moriri (Lake Moriri) we get to sight some exotic migratory birds like the rare Great crested grebe, endangered Black-necked cranes, the lake is also the lone breeding home for the Bar-headed geese. Camping at the green grounds of Chumik Shilte and Kiangdam, we get to sleep under the stars and uninhabited lands of the Changthang, is a surreal experience of living, even if for few days, amongst the magnificent glacier peaks and still blue lakes. The trip ends with another scenic drive across Changthang to Leh, the main city of Ladakh, for a leisure day in Leh to relax the aching muscles after the challenging yet exciting walk. This trek is recommended for experienced trekkers who have had some high-altitude trekking experience or maintain an active lifestyle. - High altitude crossing from surreal Spiti into Changthang, the Tibetan plateau - Turquoise Tsomoriri Lake between Kiangdam and Korzok - Wild Tibetan wild Asses and rare birds at Tsomoriri - Witness lifestyle and interaction with Changpa Nomads of Ladakh - Millennium old monasteries of Spiti - 2 splendid high altitude drives through awe-inspiring scenery
