Laboon Awaits: The Magical Boat Ride

No One Piece event would be complete without a nautical journey. Lumphini Park’s lakes become the “Grand Line” for a week, letting visitors hop into fun, decorated boats for a gentle cruise in search of Laboon, the legendary whale. Organizers promise surprises on the water and perfect photo ops, so charge your camera!

Why Bangkok Is the Perfect Setting

Bustling, colorful, and endlessly imaginative, Bangkok is basically a real-life One Piece world! Lumphini Park is right in the center of the city, accessible from anywhere and always bustling with activity. On a good day, it’s the perfect place for picnicking, fitness, or just relaxing by the water. This week, though, expect it to be packed with pirates of every kind and plenty of Straw Hats!
