Coordinates: 57°42′43″N 4°03′36″W / 57.712°N 4.06°W Nigg Bay (Scottish Gaelic: Camas Neig) is a large, relatively shallow sandy bay, consisting of mudflats, saltmarsh and wet grassland, located on the north east coast of the Cromarty Firth, 5 miles (8 km) east of Invergordon, in the district of Ross and Cromarty and in the Scottish council area of Highland. At low tide, the Sands of Nigg are exposed. Nigg Bay can be said to start at Balintraid pier - probably the oldest pier on the Cromarty Firth - built by Thomas Telford in 1821. There is a wartime mining base alongside the pier and a series of coastal gun emplacements on the road to North Sutor.
Nigg Bay is an extensive area of mudflats, saltmarsh and wet grassland on the Cromarty Firth. Visitors between October and March are sure to see countless wading birds and wildfowl, such as bar-tailed godwits, knots, pink-footed geese and wigeon, feeding and roosting on the mudflats, moving with the tide in and out of the bay.
The best time to visit is two hours either side of high-tide, as the birds are pushed up closer to the hide.
