The Kedar Tal trek is 8 days and 7 nights, and it gains height quickly. The way the days are laid out is what makes that comfortable.
Day 1: Dehradun airport to Gangotri. The drive goes via Uttarkashi (1,158 m) and takes 10 to 11 hours, so we sleep in a hotel in Gangotri (3,048 m). The road runs along the Bhagirathi valley, and Harsil, Dharali and Bhaironghati lie on the last stretch.
Day 2: Gangotri. A full day at 3,048 m with an easy walk of 2 to 3 hours to Surya Kund (3,100 m). Walk slowly, drink water and tell your leader early about any headache or nausea. Nothing else is planned, and that is deliberate.
Day 3: Gangotri to Bhoj Kharak (3,496 m). About 7 km in 3 to 5 hours, through birch forest and over the tree line to a camp on a meadow. Poles help on the steeper parts. Carry a rain layer within reach.
Day 4: Bhoj Kharak to Kedar Kharak (4,279 m). Only 3 km, 2 to 3 hours, but it is the biggest gain of the trek. You cross a few rockfall zones and arrive early, so the afternoon is for resting, layers and water.
Day 5: Kedar Kharak to Jogin ABC, with Kedar Tal on the way. About 8 km in 4 to 6 hours. This is the glacier section and steep ridge walk, then the lake at 4,708 m below Thalay Sagar and Bhrigupanth. We do not linger at the lake, then continue to camp at Jogin ABC.
Day 6: Jogin ABC to Kedar Kharak. About 8 km in 5 to 6 hours, with a short morning exploration in the upper valley before heading down.
Day 7: Kedar Kharak to Gangotri. About 12 km in 5 to 7 hours via Bhoj Kharak, the longest walking day. A hot wash and a hotel night in Gangotri follow.
Day 8: Gangotri to Dehradun airport. Another 10 to 11 hours by road. Leave early, and plan your onward travel with a buffer for road delays.
The 8-day plan carries no separate reserve day. The rest day at Gangotri and the short climb on day 4 do the acclimatising. If you have a tight flight, tell us your dates and we will plan the buffer around the drive.
