After reaching Sandakphu Top, Land Rover will drop you to your pre booked hotel or trekkers hut. There the Land Rover stays for rest of the day. If you want to stay at Sandakphu for one night, then next day morning after breakfast the same Land Rover will take you back from the Sandakphu Top. But if you want to tour Phalut with Land Rover, then morning after breakfast it will drive you upto Phalut Top.
The drivers generally come down to spend the night leaving the Land Rover on top. A few Km down from Sandakphu, there is a small settlement where all Land Rover drivers relax and spend the night. At morning they again climb up by taking a lift from any of their fellow driver.
Here one thing to note that as the Land Rover stays the entire night under the open sky and extreme cold, in the morning they sometime take time to start. So little patience is expected from the travelers.
