The Siju Cave is located in the West Garo Hills district of Meghalaya at an altitude of about 500 m above sea level. It has one main cave which can be entered through a narrow opening on the northern side, about 12 feet high. The main cave is about 300 feet long and terminates at a perpendicular cliff from where one can have a spectacular view of the surroundings. On one side of this cliff, there is also another small opening that leads to a second but much smaller cave.
Siju Cave Wildlife Sanctuary is a beautiful natural landscape with an abundance of wildlife. Inside the cave are found several species of bats, but the most common are the fulvous fruit bat, greater short-nosed fruit bat, cave swiftlets and common pipistrelle.
The main attraction in this sanctuary is a spring called 'Siju Patti' which feeds a perennial stream. This place is also famous for its Chinese fan palm (Livistona Chinensis), an endangered flowering plant that is used in traditional medicine.
The best time to visit Siju Cave Wildlife Sanctuary is between November and February when you can spot several migratory bird species in one day. It is also an ideal place for photography during this time of the year. If you visit outside these months, then you may need to carry your own binoculars as none are available on site. You will find many other animals like barking deer, wild boar and leopards around the cave.
