Pulau Ubin is
the second largest of Singapore's offshore islands. (The largest is
Pulau Tekong, just next to Pulau Ubin).
Lying in the Straits of Johor opposite Changi, Pulau Ubin has been
described as being boomerang shaped. About 1,020 ha or 10.2 sq km
in area, it is about 8km at the longest length, and its breadth varies
from 1.3-1.7km. The highest point of Ubin is Puaka
There are two major offshore islets near Ubin: Pulau
Sekudu or Frog Island (opposite Chek Jawa), and Pulau Ketam (opposite
Ubin Lagoon Resort)
Pulau Ubin has several rivers meandering through it; the main ones
being Sungei Besar and Sungei Mamam.
Pulau Ubin is made up mostly of granite. This fact has shaped much
of the island's activities. Even its name arises from it. One account
says that this kind of granite was used to make floor tiles, called
"jubin" in Malay. Another says "Ubin" was the
Javanese term for square stone.
