Oil rigs in the Cromarty Firth

The Cromarty Firth is an arm of the Moray Firth which separates the Black Isle from Easter Ross. It takes its name from the burgh of Cromarty near the mouth of the firth. The banks of the Cromarty Fiirth are in Cromartyshire and Ross-shire; the main body of Cromartyshire is on the Black Isle on the south shore of the firth but with parts of each shire on either coast.

The entrance to the Cromarty Firth is guarded by two precipitous headlands called "The Sutors" from a fancied resemblance to a couple of shoemakers (in Scots, souters) bent over their lasts; the one on the north stands 495 feet high and the one on the south 463 feet. From the Sutors the Firth extends inland in a westerly and then south-westerly direction for a distance of 19 miles. Excepting between Nigg Bay and Cromarty Bay where it is about 5 miles wide, and Alness Bay where it is 2 miles wide, it has an average width of 1 mile. The southern shore of the Firth is formed by a peninsula known as the Black Isle. Good views of the Cromarty Firth are to be had from the Sutors or Cnoc Fyrish.

At its head the Firth receives its principal river, the River Conon, other rivers include the Allt Graad, Peffery, Sgitheach, Averon and Balnagown. The Dingwall Canal remains connected to the Firth, although it is now disused. The principal towns on its shores are Dingwall (Ross-shire) near the head, Cromarty (Cromartyshire) near the mouth and Invergordon (Ross-shire) on the north shore. The villages of Evanton, Alness and Culbokie are nearby.

There is one bridge, the A9 road crossing between Ardullie and Findon. In the past there were several ferries across the firth (for example at Foulis) but now there is only one, a four-car ferry that runs between Cromarty and NIgg during the summer.

The firth is a designated as a Special Protection Area for wildlife conservation purposes. Many bottlenose dolphins, harbor porpoises, grey seals and harbour seals live here while minke whales, seasonally migrate. Larger animals such as humpback whales, northern bottlenose whales, long-finned pilot whales and common dolphins are seasonal or occasional visitors, as are large fish such as the sunfish and basking sharks.[1]

The Firth forms one of the safest and most commodious anchorages in the Highlands, and Invergordon was at one time a major base for the Royal Navy's Home Fleet. The Firth was the scene of the Invergordon Mutiny in 1931. Remnants of the Navy remain, such as the disused airfield near Evanton (now an industrial estate) which was built to take aircraft from the fleet carriers while they were at anchor. During the Second World War, there was a large training and operational base for Catalina amphibians and Sunderland seaplanes, which extended from Invergordon to Alness point - also now an industrial estate. A memorial to the men who were killed on operational missions was placed at this industrial estate in 2001. A propeller from a Catalina was found and restored by RAF apprentices and now resides in the village of Alness. The tennis courts on the industrial estate are the only remaining parts of the estate which date from the War.

Oil and renewables industry

Cromarty Bridge across the Firth

At Nigg there is an important North Sea oil and renewable energy centre owned by Global Energy Group since 2011. The yard with a dry dock for repairing and fabricating oil platforms, was opened in 1972 as a joint venture between Brown & Root (as it then was) and construction giant George Wimpey. Today the yard is known as Nigg Energy Park.

Elsewhere along the firth are facilities for cruise ships, oil processing, and bulk cargo handling.
