*Note: This trick is only available after the 1.02 update
This trick allows you to access and enter the GenkiBowl VII Island location without having the Genki Bowl DLC.
To access the location, grab a vehicle (flying is faster), and travel toward the large Statue in the ocean on the east side of the map. Once you are near this location, continue flying East/Northeast out into the ocean, until you reach the barrier (on screen text will tell you to return to the map). Once there, simply exit your vehicle, and begin swimming. Continue swimming until you are prompted to ‘Warp to Shore’. You will now be inside the GenkiBowl arena.

how the hell do i get out?
Hey guys i’ve tried it about five times in a row and still end up back in steel port, do you have to have all the genki activities completed ? i’ve read all the descriptions of how to get to the island and still cant get there. I have xbox 360 if that matters
