The best time for the Sar Pass trek is a three-month conversation: April, May and June are the entire season, and each month serves a noticeably different trek. The famous 100-metre snow slide, the ridge camps above the clouds, the state of the trail through Grahan's forests — all of it shifts week by week through spring. Here's the honest breakdown.
Sar Pass in April: maximum snow
April is the white month. Snowfields start below Min Thach, Nagaru camp at 12,500 ft sits fully in snow, and the slide off the pass is at its longest and fastest. Nights are cold — -5°C and below at Nagaru — and days hover 10–15°C lower down. Pick April if snow is the point; micro-spikes and gaiters are provided and needed.
Sar Pass in May: the balance
May is the crowd-favourite compromise: reliable snow on the pass day and the slide still excellent, while Grahan's forests and the lower camps turn green and the nights ease. This is when the trail is at its most photogenic — white above, rhododendron red below. Batches fill first for May weekends every year.
Sar Pass in June: greener and gentler
Early June still crosses good snow up high, but the slide shortens and softens as the month runs on. In exchange you get warmer camps, flowering meadows at Biskeri Thach and the friendliest conditions for first-timers nervous about cold. By late June the snow is slush and the monsoon is knocking — the last batches run, then we close the route.
Why doesn't Sar Pass run in July or later?
Monsoon hits the Parvati valley hard: rotting snow, slippery forest trails and clouds where the views should be. The route then sleeps under fresh winter snow until the following April. There is no autumn season on Sar Pass — that's what makes the spring window precious.
Cost and booking
The 5-day trek from Kasol costs ₹10,999 + 5% GST per person, with meals, camping gear, snow equipment and permits included. April–June dates are live on the Sar Pass trek page — and if you want the slide at full length, don't wait for June.
