All depends on what you want to do over there. Every hill offers a good amount of adventure and fun. Kodaikanal is none the less . There are good trekking points. You can trek upto Penguin Nose . You can enjoy lovely weather over there at early morning and evening around the lake. Don't know of any adventure sports over there but trekking would be fun. Last time when I went there , the place has become dirty. Hope they would have cleaned it by now.
Hey Pradeep, Obviously it's a great time to visit this princes of hills stations in Tamil Nadu .... Here are places you shouldn't miss when you travel to Kodaikanal:- Dolphins nose Church in Kodaikanal Echo and suicide point Vattakanal falls.. Happy Travelling Bro!!!
