It is an Atlantic Ocean beach extending from the Smallrock (Roc Beag) and Blackrock in the North to Carrahane at its southern edge.
Carrahane lagoon on the south end, famous for migrating birds and the Roger Casement landing.
Historically, Banna Strand is associated with Roger Casement who was captured on 21 April 1916, having landed from a German U-boat.
A monument for Casement and another man, Robert Monteith, stands near the dunes with the inscription: "At a spot on Banna beach adjacent to here Roger Casement - Humanitarian & Irish revolutionary leader - Robert Monteith & a third man came ashore from a German submarine on Good Friday morning 21 April 1916 in furthering the cause of Irish freedom."
A decision was taken by the 1966 Banna Strand committee to deliberately omit the name of the "third man" from the monument because, following his capture, he turned "King's evidence."
