Goonhilly Downs is a Site of Special Scientific Interest that forms a raised plateau in the central western area of the Lizard Peninsula in Cornwall, England, UK. Situated just south of Helston and the Naval Air Station at Culdrose, it is famous for its Goonhilly Satellite Earth Station, the largest in the world. The large satellite dishes are an iconic landmark, and can be seen for miles.

A couple of miles west of the BT site is another SSSI and nature reserve, owned and managed by the Cornwall Wildlife Trust. This reserve is prime Cornish heath (Erica vagans) with ponds and willow fen. Early Bronze Age barrows are present and there are several ancient 'turf-hut' circles. There are remains of buildings which were part of RAF Dry TREE and later RAF Trelanvean, used during the Second World War. Both adders and stonechats are commonly sighted here.
Half a mile before the BT Satellite dishes is Goonhilly Craft Shop and Tea Room. Set back from the road, the building was constructed in the early 1960s by a local farmer. The land was originally part of the nearby Trelowarren Estate. Planning permission was granted to build a 4-bedroomed bungalow and petrol station, and it was known locally as 'Telstar Cafe'. (Telstar is the name of various communications satellites, including the first ever such satellite able to relay television signals.) 'Telstar Cafe' formerly had a petrol station but petrol sales have been taken over by Tesco in nearby Helston. 100,000 people a year visit BT's nearby FutureWorld@Goonhilly (now closed) and many of them also call into the Craft Shop and Tea Room before making their way back from Goonhilly.
Goonhilly Downs also serves as a landing point for the SEA-ME-WE 3, the longest submarine cable on Earth
