Sulani

Sulani is an island paradise introduced in the Island Living Expansion Pack for The Sims 4. Featuring ten residential lots and three public lots, the island chain encourages relaxing lives and plenty of beach entertainment. No lot is overly busy so people are sometimes few and far between; that may or may not be what your Sims are looking for.

Sims who don't live in Sulani can freely visit anytime through the world map. Most of the other features added to The Sims 4 in the Island Living Expansion Pack can be used anywhere, but some (such as the Island Conservation system) can only be applied while the Sim is actively on the islands regardless whether they live their or not.

Sulani doesn't hold too many secrets, although the Mua Pel'am island does feature a nearby cave that can be explored. When Sims check it out, there is a chance they can get some decent if small rewards such as Mermaid Kelp to turn Sims into Mermaids.

The cave may be a little tough to find at first before you're used to the area. As seen in the screenshot above, it's located against the rock face just near the lot premade with a shipwreck residential lot. If you want to explore it often, you may want to consider taking over that shipwreck lot.
