Zennor Head is on the South West Coast Path, which follows the cliff edge closely, skirting the entire perimeter of the headland.

[1] The headland is bordered by Cornish granite hedges, and the farming system dates from about 4000 BC, the time of the Bronze Age in Cornwall.

[3] Zennor Head was mined extensively for copper and tin in the 19th century, and drainage adits remain visible on the eastern side.

[4] The Southwest Coast Path was created in 1978, and runs along the top of Zennor Head as part of its 630 miles (1,010 km),[3][5] following the edge of the cliffs closely.

[11] The Killas strata, which is exposed over the majority of Zennor Head, is a sedimentary rock formation[12] laid down in the Devonian period, between approximately 415 and 375 million years ago (myr).

[13] Zennor Head is on the surface boundary of the so-called "Land's End Granite", part of the Cornubian batholith which dates from 279 to 274 myr.

[3] The headland is primarily covered with grass, as well as heather (Calluna vulgaris), bracken (Pteridium aquilinum), thyme (Thymus polytrichus) and western gorse (Ulex gallii).

[3] There are also typical coastal flowering plants such as kidney vetch (Anthyllis vulneraria), sea campion (Silene uniflora), and thrift (Armeria maritima).
