You can't. Babord is not open and there is no way to get inside. Infact the only thing that's over there is a few old buildings left over from the old classic map.
If Babord does open up, it will be announced in the in-game news...
All indications are that it will be a new location.
Once before the swamps were upgraded there was a large clay platform and no houses at the babord location . Just like before the destiny update. The update of the swamps was certainly also one reason to modify the terrain for the new location.
New wayout, two kids, new caves to babord.
But I would welcome an update before babord for:
cave at Battle Tower in Onnet Town.
battle arena v Graal city
And some other outdated textures that don't fit into the game with the beautiful new ones.
I would be very happy if my idea with fishing and boating came out and took part in the update for baboard. It will definitely look a lot different than from the original game, but even better.
since 2016 there are only the best updates, quests, etc
