All 4 Hidden Worlds and How to Get There In The Sims 4
This guide will provide you with all four hidden worlds in The Sims 4. You will also learn how you can get there.
1. Sylvan Glades
First, go to an area in Willow Creek named Crick Cabana. You will find a magical-looking tree called the Sylvan Tree. View the tree a couple of times until new interactions like “Water” unlock.

Discuss nature with the tree and chat about the tree's roots. Eventually, the secret door will be revealed.

Welcome to the land of Sylvan Glades. You can find new collectibles such as snapdragon plants to harvest, toads fishing, etc.

2. Forgotten Grotto
Go to one of these two areas in Oasis Springs: Affluista Mansion or Desert Bloom Park.

There will be an abandoned mine in both areas requiring level 10 Handiness to open.

You can increase your Handiness skill.

Use a hammer to break and open the mine. You can harvest plants, dig for minerals, fish, etc.

3. Deep Woods (TS4 Outdoor Retreat)
Take a vacation to Granite Falls from your phone. After arriving, head straight into the forest.

Enter the bushy cave.

Welcome to the Deep Woods!

Here you can:
- Meet the hermit, harvest herbs and berries

- Go camping and fish new types of fish

4. Planet Sixam (TS4 Get to Work)
There are two ways to get here.
Method 1: Scientist Career
Join the scientist career and work until your 11th breakthrough (Scientist Level 6). This allows you to invent the portal.

After the 11th breakthrough, keep working until promoted to level 10. Upgrade the portal and go straight to it.

Method 2: Rocketship
Build a rocket ship and increase your Rocket Science skill to level 10. Upgrade your rocket and blast off!

Behold Planet Sixam!

You can:
- Meet aliens and find small alien critters

- Find and harvest three unnatural edible plants: Glow Orbs, Quill Fruits, and Fang Flowers

- Find minerals, polish geodes, and collect crystals

There is no phone service at Sixam, except calls from your wrathful boss.
