Tremone is an area on the Inishowen Peninsula in County Donegal. Most of Inishowen's population inhabit the peripheral coastal areas, while the interior consists of low mountains, mostly covered in bogland, the highest of which is "Sliabh Sneacht" (from the Irish, meaning Snow Mountain) which is 619 metres (2,030 feet) above sea level.

Inishowen has several harbours, some of which are used for commercial fishing purposes, including Greencastle, Bunagee and Leenan. A seasonal ferry service crosses the Foyle, connecting Greencastle with Magilligan in Derry, while another crosses the Swilly, connecting Buncrana with Rathmullan. The village of Fahan has a privately built Marina.

There are several small outlying islands off the Inishowen coast, most notably Inishtrahull and Glashedy islands, both uninhabited, although the former was inhabited until the early twentieth century. Inch, located in Lough Swilly is technically no longer an island, as it has a causeway connecting it to the mainland at Tooban, south of Fahan.
