Shimla Water Catchment Wildlife Sanctuary has a long history of conservation and is considered to be one of the densest forests of Asia. It has been conserved for more than past 135 years. The trek is fairly easy and relaxing as you will walking on a rough narrow road which is leveled with almost no ups and downs. The sanctuary offers opportunities for wildlife tourism with breathtaking vistas to nature lovers with lots of potential for animal and bird sighting. Ghoral, barking deer, langoor, Porcupine and common leopard wander freely in this sanctuary. You can also see specked wood-pigeon, Himalayan woodpecker, yellow-billed magpie and Koklass pheasant if lucky. After an approx 2 hrs walk you will reach Seog (7 kms from entry gate) where the water tank with the capacity of approx 5 million gallons still stands which was built by British back in 1901. Though not in use now, you can still marvel at British engineering done more than 100 years ago. From here, trek uphill through a small trail for approx 10 to 15 minutes through dense forest to reach Seog guest house again built in 1901 (though recently renovated). On way visit a small card room built for the pleasure of British at the same time. On reaching the guest house, have your packed lunch under the open sky with sounds of the jungle. After lunch, proceed downhill until we catch up with the main road for our returning journey. The sanctuary has a huge variety of trees like ban-oak, moru-oak, kharsu-oak, kail, spruce, silver fir, Rhododendron, Chir and Himalayan Cedar.
