Vagagmon was the destination for my 60K Trail Ultra run event, and being a first time visitor, I was hesitant to go with my wife. Finally, we decided to brave it out and we were absolutely thrilled by the experience.
What made it better was that we went on bike, and equally, the rains missed us on all days, until we got caught finally by rains on the Thrissur-Palakkad highway.
There is not much to visit as sightseeing places, but every side you look at is a sight to behold. Reasonable homestays to exotic staying places, trekking routes, friendly locals, et all.
2 things to note: (1) Pure vegetarian be warned that there are no 'pure veg' restaurants. (2) no fuel stations in Vagamon Town, have to make atleast 30kms for fuel (or fuel in cans available for emergency). (3) Try avoiding during weekends if you don't like crowding.
A great destination for visiting as friends or as a couple or couple of families.
The Kerala roads were equally good, as we deifted from Adhirampally falls to Vagamon to Kottayam and back (from Coimbatore).
