The village is served by a small public school (Warrimoo Public School), a private school (Wycliffe Christian school), a railway station and several shops including a post office. Warrimoo has a few escarpments and views that are quite untapped by tourism due to the size of the suburb and the "tucked away" nature of the bush trails where the lookouts are placed.
In 1898, a railway station platform named Karabah was built in the area to service a developing estate, possibly sharing the same name. It had closed before World War I, but in 1918 a new station was built, not much further down the Blue Mountains line, named Warrimoo. This station burnt down in a bushfire in the 1950s and was subsequently rebuilt. Warrimoo came to national prominence during the devastating Black Christmas bushfires of 2001 that destroyed seven houses in Cross Street and one in Terrymont Road.
