It is the only crossing between New Austin and Nuevo Paraiso that is not part of the train system. The other two crossings, Frontera Bridge and Butter Bridge, are primarily intended for trains, although the latter has small pedestrian walkways and both can be traversed by the player.
It is possibly called "Berry on a Twig" (English translation of Ramita de la Baya) due to the fact that the island looks like a berry, and the bridges resemble twigs or sticks. It could also be a a subtle sexual reference to male genitalia, which can be referred to by slang as "twig and berries".
If the player captures Javier Escuella alive, he will be handed over to agents Ross and Fordham here. By making the handover at the border, this avoids any out-of-jurisdiction activities by the US federal agents.
Ramita de la Baya, along with the unnamed island Thieves' Landing is located on, are the only accessible islands in the game.
As with all the other New Austin/Nuevo Paraiso crossings, the signs say "Entering Mexico" in America, but "Leaving Mexico" in Mexico (rather than "Entering America").
The US/Mexico border line is located under the bridge on the Rio Bravo side, which makes the island Mexican territory. When the location "Ramita De La Baya" pops up on the top of the screen, the game registers the player as being in Mexico.
Sometimes, people can be found camping on the island.
There is always a fire lit on the southwest corner of the island.
The game will register the player as being in Perdido if the player walks across the lower bridge, or wanders too long in the very southern part of the island.
