Behbane Head: The section of coastline between Dunseverick and Portballintrae is best known for the Giant's Causeway, a pavement of columnar basalt sticking out into the sea. A sea kayak provides the ideal viewpoint, if only to avoid the hordes of tourists. However, this trip reveals that the remarkable geology isn't restricted to the Causeway itself, with spectacular geology all the way around the headland. There can be downdrafts off this coastline and wind funnelled out of bays in strong offshore winds. There can be significant tidal streams and overfalls off Benbane and Bengore Heads.
