Helford River

The Helford River (Cornish: Dowr Mahonyer) is a ria (flooded river valley) in Cornwall, England, fed by small streams into its many creeks. There are seven creeks on the Helford; from west to east these are Ponsontuel Creek, Mawgan Creek, Polpenwith Creek, Polwheveral Creek, Frenchman's Creek, Port Navas Creek, and Gillan Creek. The best known of these is Frenchman's Creek, made famous by Daphne du Maurier in her novel of the same name. A little further up river is Tremayne Quay, built for a visit by Queen Victoria in the 1840s which she then declined to make, allegedly because it was raining.

The river has long been an important industrial and agricultural marine highway serving local mines, farms and quarries as well as the local fishing industry. Most of this industry has now gone, although commercial fishermen still use the river to land their catch, amounting to about 1 million pounds sterling a year, and the oyster fishery is being revived. The industries have largely been replaced by tourist activities, in particular those relating to the sea, although at the head of the river the landscape is dominated by the extensive operations of Gweek Boatyard and the base of marine drilling and construction company Fugro Seacore, although the latter has moved its main base to Falmouth. These businesses now dominate the head of the river where once coal and timber were landed. On the opposite bank is the Cornish Seal Sanctuary, where injured seals are nursed back to health before being released to the freedom of the Atlantic Ocean. The traditional 'heavy' industries have been replaced by 'lighter' businesses catering for the many tourists who visit the area.

The area falls into a Special Area of Conservation, Site of Special Scientific Interest and Area of Outstanding Natural Beauty. The growth of eco and sustainable tourism have seen the development of tourism by Helford River Expeditions focusing on the natural surroundings. The National Trust play an important role with their strategy. Natural England (formerly English Nature) play an important part in protecting and monitoring the area. The river is unique in that it is not wholly managed by a specific port or river authority, but brings together major environmental groups and organisations interested in the protection and development of the river, and introducing and recommending safeguards, such as Helford River Marine Conservation Group.
