Everything about Coorg is nice.
The people are very friendly -- we stayed at a homestay, with a very pleasant family who made us feel very much at home.
The weather is very bracing (though not during the rainy season apparently) and the main town of Madikere is small unspoilt, untouristy and un-trafficky.
The coorgis (actually called coorgs, or kodavas) are a people with lots of personality and character and its fun to read about them and see the artifacts of their existence.
There are plantations with peaceful quiet atmosphere and long walks, although we didn't get to do much of that on this trip.
There's a lot of interesting stuff around: beekeeping, the origin of the Cauvery, other Cauvery stuff, and a Tibetan monastery , to name a few.

Go to Coorg. I'm glad we did.
If you want to pool together and buy a holiday home there, add a comment.
