Subtropical Arc – Ishigaki, Kaohsiung & Keelung

About this cruise

A lot can happen in 5 nights. This sailing from Naha on July 8, 2026 visits Ishigaki, Kaohsiung and Keelung and makes every day count. A few ports come in quick succession, which is great for sightseeing but means you'll appreciate the sea days when they arrive. Bullet trains visible from the harbour, cherry blossoms, and thousands of years of history. East Asia is a lot to take in. Don't rush through Keelung, which is known as Taiwan's rainy harbour of night-market magic. Port time is tight at about 5 hours each. Pick your favourites and save the rest for another trip. At 114,147 gross tons, Costa Serena is big enough that you can find a quiet corner or a crowd, depending on your mood. Families and groups will find plenty to do: waterslides, shows, multiple pools, and something for every age. If you can, add a night in Naha before boarding. It's a good city to wander. The timing works well too: warm evenings on deck, late sunsets, and a lively atmosphere. All told, 3 ports across 5 nights covers a lot.
