Get a map of the tram route at the port as a lot of the tourist attractions have stops nearby we caught the tram then the muesum and the castle were a short walk away. However Kochi is not a huge city so it is probably not that far. Savings on tours and activities. Sorry don't know where the Kochi cruise port terminal is located, something you need to check on the cruise. There are some similarities but always very interesting with great views from the top. I would allow 60-90 mins to view Kochi Castle, depending on how many Japanese castles you have visited previously.。
