Facing the Atlantic Ocean, the narrow rocky inlet of Port Quin provides a naturally sheltered harbour for sea-going vessels. The cove gives its name to Port Quin Bay, a 2.5 mi (4.0 km) stretch of coast that extends from Kellan Head to The Rumps.
During the medieval period, boats from Port Quin often sailed to Wales trading coal, manure, antimony, lead and building ashlar. The cove was from where granite from Lundy Island - used to build the tower of the parish church at St Endellion - was unloaded. The local economy was based primarily upon the pilchard season that operated from August to December. Fresh catches were placed in several large drying sheds in the village before being transported for sale. Farming and small tin mines were also important sources of revenue.
The size of the remaining fish cellars indicates that Port Quin was once a prosperous village. But by 1841 it was entering decline, a census recorded it had a population of 94 people and 23 houses. The community was slowly moving to neighbouring villages because of poor pilchard and herring seasons and the closure of local mines. Many emigrated (via Padstow) to Canada. As Port Quin dwindled to the size of a hamlet, its demise gave rise to the local legend of disaster at sea. It states that one Sunday - breaking the Sabbath - all the men of village put to sea but were lost in a great storm that destroyed the entire fishing fleet.
In February 1700 the East Indian ship Thornton was wrecked at Port Quin.
The harbour is surrounded by 3 local farms Roscarrock, Trevigo and Scarrabine all run by local families. some of Port Quin and a few small fields around the hamlet are owned by the National Trust for Places of Historic Interest or Natural Beauty; the Trust rents out several of the stone cottages as self-catering holiday accommodation. The South West Coast Path closely follows the coastline of the inlet. Port Quin is popular with walkers and kayakers and there is a small car park, which during the Summer season has a small mobile vintage Cafe, on the lane which leads from Port Quin to the village of Trelights. There is a sea kayaking company based in the harbour called Cornish Coast adventures that runs tours between Easter and October and explores the old Antimony mines and the local coastline.
