If you have more time, you can visit the quaint town of Kovalam or the backwaters of Alleppey. However, if you have less time, you can visit only Varkala Beach and Janardana Swami Temple. It is best to visit Sivagiri Mutt and Kappil Lake on weekdays as they tend to be less crowded. Please check with the locals about the closing timings of the places before visiting them.
