Reach Samrad, the base of the trek, early in the morning. Relax and recharge yourself in the village.You should begin the trek by afternoon from the base. It is only then that the valley starts seeing sunlight. It is advisable to start the trek during mid-day. You can hire a local guide too if you are not trekking with a group.The initial trekking can be done effortlessly as there is no uphill climb. After walking for a km, you see the entrance of Sandhan Valley. The valley is five to seven metre wide, blocked on the sides with vertical rocks of a height up to 30 metres. The narrow valley is also the course of a seasonal river which floods it during the monsoons, when the valley is shut down.
