Low cost tourism in kerala

Kerala have a low cost tourism. In my idea start ur travel from trivandrum first visit padmanabha temple, the zoo, priyadarshini planetarium then beach shamgumugha and kovalam howwa beach distamces these place near by 9km, local buses available at cost Rs. 9 only. Continue ur trip to kanyakumari km 75 bus fare Rs 40 only and then kumarakam boat house km 250 busfare Rs 90 only and then munnar hill station km 80 busfare Rs 60 and then guruvayoor temple km 120 busfare Rs 80 totally u have expense only Rs1500. Think make a good plan and make trip jolly
