Seaton (Cornish: '''Sethyn''', meaning little arrow after the river) is a village on the south coast of Cornwall, England, at the mouth of the River Seaton 3.8 miles (6.1 km) east of Looe and ten miles (16 km) west of Plymouth.[1] The village is in the civil parish of Deviock.[2]
The village stretches inland along the River Seaton valley. It has two pubs, a beach café. Seaton beach is mostly shingle and stretches from the river to the village of Downderry a mile to the east.
Seaton Valley Countryside Park, one of four Country Parks in Cornwall, is immediately to the north of the village. The park includes a nature trail that can be followed for nearly two miles north to Hessenford.
A Monkey Sanctuary with a colony of woolly monkeys and other rescued primates is two miles to the west.
A station was to be built at Seaton as part of the proposed St Germans & Looe Railway in the late 1930s, but the railway was abandoned without the station having been built.[3]
