The trekking hours are not fixed. The prevailing weather conditions, terrain and walking pace will determine the daily trekking hours. In general, we plan the trek for five to six hours of daily walking on average. In a group trekking expedition, it is essential for us to gauge every individual’s stamina level and plan our journey ahead accordingly. Starting the trek early is key to avoiding the midday heat and arriving at your destination early. This leaves with enough time to rest, acclimatize, and explore the Gangotri Nationa Park region.
