There are two hidden/unlockable lots in each world in The Sims 4. To unlock and enter these lots, you will need to complete specific actions, and once inside, your Sim will have access to rare and unique collectibles.
❗ Once unlocked, your current household will always have regular access to these lots.
Sylvan Glades (Willow Creek)
Sylvan Glades is Willow Creek’s hidden lot. To access this lot, you will need to visit the “Crick Cabana” lot, and head over to the Sylvan Tree behind the home. The tree is located on public space.
Once you make it to this lot, head straight to the back area and find the Sylvan Tree. This tree has special decorations around the trunk, so there’s no way to miss this out of the ordinary tree.
When you click on the tree, you will have the option to “View” it. View the tree a couple times, Water the tree about 3 times, Discuss Nature with the tree, Chat about the tree’s Roots, and a secret door will unlock in no time.
Once the secret opening appears on the tree, your Sim will have the option to explore it. This will prompt adventure like text on the screen and as long as your select the right answers, you will unlock the hidden lot.
Once you enter Sylvan Glades, your Sim will find the following collectibles: Treefish (exclusive),Cherry Tree, Pear Tree, Snapdragon, Lily, Bluebell, Strawberry, Mushroom, Basil, Minerals, Fish and Frogs.
Forgotten Grotto (Oasis Springs)
Forgotten Grotto is Oasis Spring’s hidden lot. To access this lot, you will need to visit the “Dessert Bloom Park” or the “Affluista Mansion”, and find the abandoned Mine Cave. Even though the Cave is located on public space, your Sim must have a Level 10 in the Handiness skill in order to “break” the barriers.
When you make it to either of the two lots, have your Level 10 Handiness Skill Sim look for the abandoned Mine Cave and break it open. Once the cave is open, your Sim will have the option to explore it. This will prompt adventure like text on the screen, and as long as your select the right answers, you will unlock the hidden lot.
❗ Note: Breaking open one of the two caves will not automatically make the other accessible.
Once you enter Forgotten Grotto, your Sim will find the following collectibles: Batfish (exclusive), Mushrooms, Onions, Sage, Potato, Lily, Minerals, Fish and Frogs.
