I had the chance to go to Trivandrum for a work-vacation... I went along with my darling and I loved it.
Trivandrum is a nice starting point, but few things are there to see.
Alleypey is overrated. The boat trip is nice, but if time is tight, it can be skipped.
Munnar was the highlight. I wish I had more time to enjoy there.
Kochi looked promising, but time was too short. Oh well.
