Beyond Breiðavík, Route 612 climbs up and over a plateau (there’s an extremely rough 12km gravel road off here to Keflavík) and then steeply down to the coast again before expiring a few kilometres on below the lighthouse at Bjargtangar, the westernmost point in Europe. The Ísafjörður–Brjánslækur–Patreksfjörður bus spends about two-and-a-half hours here before heading back – don’t miss it unless you can afford to wait two days for the next one.
The lighthouse also marks the start of Látrabjarg cliffs, which rise up to 441m above the churning sea as they run 14km east from here to the small inlet of Keflavík. A footpath leads along the clifftops, with excellent views of the thousands of seabirds that come here to nest on the countless ledges below. For centuries, locals would abseil down the cliffs to collect their eggs and trap the birds for food – it’s estimated that around 35,000 birds were caught here every year until the late 1950s – and, occasionally, they still do.
