56 Kms from Shillong and is known for the Giant Stalagmite formation shaped into a "Shivalinga" and found inside a cave known locally as 'Mawjymbuin' One and half Kilometres off the right hand side of the Shillong Mawsynram - Balat - Ranikor Highway, very near Weiloi Village, once comes across a unique geological formation called "Symper Rock". It is an almost flat topped loaf-shaped rocky dome, which rises sharply from the midst of the surrounding hillocks.
From its base, one has to take an exciting uphill trek to reach the summit of the rock. From the top of the hill one can see the gorgeous surrounding hills and valleys and the plain and fast moving rivers of Bangladesh.
