What do you do when you have hyperactive friends?
Go out a lot, visit lotsa places...leave your footprints everywhere and make wonderful memories (even in not-so-fun places :p)
Varkala Beach is one of the famous beaches in Kerela ,situated about 50 km from Trivandrum ie about one and half hour depending on the traffic.
The best thing to do is reach in the morning,laze around ,hop eating-shacks,walk on the beach and visit the tiny shops selling very hippie products.
Other than that there is not much to do.
