How long for the backwaters, hills and a beach, and when it is worth adding Tamil Nadu.
Ten nights is the number we come back to. It gives you Fort Kochi, a night on the backwaters, three in the hills and three on the coast, with travel days that do not eat your holiday.
Seven nights works if you choose two regions rather than three. Kochi, backwaters and beach is the easiest combination.
Beyond twelve nights, add Tamil Nadu for temple towns and Chettinad, or the wildlife of Wayanad in the north.
