Plan a Saturday ride to the southern stretch and step into an auto-rickshaw for the final leg to Kovalam. The metro keeps the inland part of the trip predictable, so you can budget more time for the beach.
Start at the lighthouse viewdeck, then drop down to the sand for a swim or quick snack at the shacks. Evening trains make the return stress-free once sunset crowds thicken along the coastal road.
Pack light, carry a beach wrap, and use UPI for the rickshaw hop—this is a low-fuss loop that turns into a full afternoon without getting stuck behind weekend traffic.
