Isla Paradiso is surrounded by 8 Hidden Uncharted Islands. These islands are covered in fog, and can be unlocked by completing certain actions in game. Once unlocked, these islands become part of your active household’s real estate as the fog recedes. They can be used as 2nd homes, or even converted into resorts for profit.
For more information on Island Paradise and its features, see our Sims 3 Island Paradise Game Guide.
❗ If your household moves to a new town, it would be beneficial to sell these properties prior to moving. Once you move your active household to a new town, all real estate is removed the household.
