Urbania
Urbania is the 1st area (after tutorial) to be unlocked, it looks like a more rundown area and it is where the player meets many new Urbz.

Sim Quarter
Sim Quarter the 2nd area to be unlocked, the Sim Quarter is a farmer's market/pier. At the end of the last goal of the Sim Quarter, Daddy Bigbucks tosses the player's Urb into the water.

Bayou
The player's Urb wakes up here after being tossed into the water, and all the missions are about escaping and helping out the two residents.

Paradise Island
Paradise Island is a small island with a beach. It has a small store which sells tiki themed items, and a hammock for the Urb to sleep on.

Splicer Island
Splicer Island is only included in the DS version. After 10 days, Futo Maki has used the monkeys in the ruins and worked on it. Splicer Island will be rebuilt and now the player can do all of the good stuff which includes gene splicing and pet contests.
