A Kerala trip plan for 5 days should ideally have 1 day in Kochi for historic sightings, 1-day Alleppey for experiencing the backwaters and some amazing clean beaches and 2 days in Munnar for blissful Western Ghats experience. On day 5, drive from Munnar to Kochi via Athirapally Falls. That's what I suggest because I love Munnar. However, you can squeeze in Thekkady on Day 3 and skip Athirapally Falls. If you are visiting Kerala for the first time and have only 5 days, I highly recommend this packed 5-day Kerala trip by Saffron India Tours.
