Coast is a BBC documentary series first broadcast on BBC Two television in 2005. It covers various subjects relating to both the natural and social history of the British coastline and also more recently, that of Britain's near neighbours. The seventh series followed a different format from previous series. In 2016, reports from the show were repackaged as Coast: The Great Guide (known as Coast Great Guides when broadcast on BBC Four in 2021), an eight part series on BBC Two. The series is a collaboration between the Open University and BBC Productions, Birmingham. It is also known as the placeholder programme when BBC2 is under a fault in programming. In December 2013, the first reversion of the series format, Coast Australia, was screened on The History Channel in Australia. Hosted by Neil Oliver, it was the second highest-rated show in the history of the channel. It started airing on BBC Two from 14 May 2014; series 2 was aired in 2015. Coast New Zealand aired in 2016. A similar show, Arfordir Cymru (Wales Coast), is broadcast on the Welsh-language broadcaster S4C and hosted by Bedwyr Rees; three series have aired so far, each of six 23-minute-long episodes, travelling in Pembrokeshire (2014), the Llŷn Peninsula (2015), and Cardigan Bay (2017). In 2020, BBC Studios produced a refresh of the original series called Our Coast, presented by Adrian Chiles and Mehreen Baig. The new series featured Dumfries and Galloway/South Ayrshire, County Down, Anglesey, and Liverpool.
