The San Luis River is a river featured in Red Dead Redemption and Red Dead Redemption 2.


It is a major river system that forms the natural, geographic, and political border between the New Austin and Nuevo Paraiso territories, separating the United States from Mexico. The river flows out from Flat Iron Lake. This river is used in the Outlaws to the End DLC in multiplayer mode, in the Cooperative Mission "The River". It is also the central location of the singleplayer mission "We Shall Be Together in Paradise", in which John and Irish cross the river on a raft.

There are three major crossings over the River: Butter Bridge, Frontera Bridge, and Ramita de la Baya.

This location does not count toward 100% Completion.


  • The San Luis river may be based off the Rio Grande river in the east near Hennigan's Stead, and the Colorado River in the west near Gaptooth Ridge. Both Rivers seperate Mexico from the U.S at points, with the Colorado River seperating California from Baja California and the Rio Grande seperating Texas from Coahuila and Chihuahua.
  • The river flows into the Sea of Coronado, which is in the far western part of Gaptooth Ridge.
  • Until the player completes the mission "The Assault on Fort Mercer", the river cannot be crossed.
  • This is one of the few areas where ducks can be found.
  • In Redemption II, spending time on the northern shore adds brief bits of Nuevo Paraiso's ambient soundtrack from the first game into the background music.
