In the east, Cape Palmerston National Park protects the landscape surrounding Mount Funnel and Cape Palmerston. To the west is the Hatfield Range known locally are the Koumala Range. A gravel road over this range provides alternate access to the Sarina hinterland and was the only route available for several years after the paved route over the Sarina range was destroyed by landslides that occurred during Cyclone Debbie. The main rail line between the Bowen Basin coal mines and the port of Hay Point also passes over this range with speed restricted to 60 kilometres per hour (37 mph) on the downhill section of line, because of several derailments which have occurred in this section of track.
There are a number of neighbourhoods within the locality, including:
The town name Koumala originally derives from the name of its railway station, which was named in 1914 after a sugar property used by Alfred H. Burbank, a sugar grower and surveyor, using a Fijian word meaning sweet potato.
The neighbourhood name Inneston comes from the Inneston railway station, which was named by the Queensland Railways Department on 25 November 1911 after Alexander (Alex) Innes (6 April 1866 - 24 August 1948).

The neighbourhood name Karremal comes from the Karremal railway station, which was named on16 December 1920. It is an Aboriginal word meaning heat.
The neighbourhood name Loloma comes from the Loloma railway station, named on 19 November 1914.
The name Yukan is an Aboriginal word meaning rain.
History
British colonisation at Koumala began in the early 1860s when Mark Millet Christian established the Kelvin Grovepastoral farming station. In 1867, after some Aboriginal people had speared cattle at this pastoral lease, the Native Police troopers chased members of the clan to some islands offshore and when they tried to return to the mainland "such a lesson was administered" to keep them from "committing outrages in that locality".
Koumala State School opened in August 1922. The railway goods shed and associated huts doubled for school purposes from 1922 to 1923 when a proper school house was built, as well as for social functions until a hall was built.
Yukan State School opened on 1929 and closed circa 1942.
