Gran Hermano 12+1: La Re-vuelta was broadcast on May 30, 2012 and ended on June 13, 2012.

[1] On May 24, 2012, during the main show of the Gala for Gran Hermano 12+1, the host Mercedes Milá confirmed that the Gran Hermano house will open again just three days after the Gran Hermano 12+1 finale, this time however with former housemates from last season of Gran Hermano.

The grand prize of this season is €20,000 and every ex-housemate from Gran Hermano 12+1 could win the prize.

From 21 ex-housemates, Arístides Alonso, Juan Molina, Noemí Merino and Zulema Ibáñez declined the offer to enter the house again due to occupational or personal reasons.

Pepe Flores, the eventual GH12+1 winner, did not participate in the "Re-vuelta".
