Earlier there were 3 Slots in Gulmarg Gondola Phase-1 [9-11 , 11-1 , 1-3] & Only 1 Slot in Phase-2 [9 AM to 3 PM ]
It means you have now two slot option for Phase 2. In phase1 you have three options.
The decision of time slotting is important as you have to reach on the assigned Date & Time.
At all times reaching Early and First slot is recommended and preferred rather than the 2nd Slot which is selected by most of the guests.
For Summers
In Summers the day-time is more in Kashmir so you can choose even the second or third slot but if you have Second phase booked then Go for First 2 slots only.
For Winters
Normal shoes in Summers and Long boots in Winters
They should avoid Phase-2
This is on high altitude so weather changes are unpredictable.
