If you have more time in Kochi, consider visiting the St. Francis Church and the Jewish Synagogue in addition to the attractions listed. In Varkala, you can also take a day trip to the Ponnumthuruthu Island or indulge in some Ayurvedic treatments at one of the local spas. If you have less time, skip the Anjengo Fort and Cliff Walkway, and spend more time relaxing on the beach or exploring the town.
