In modern times, St Kilda's only settlement was at Village Bay ( or ) on Hirta. Gleann Mòr on the north coast of Hirta and Boreray also contains the remains of earlier habitations. Although the sea approach to Hirta into Village Bay suggests a small settlement flanked by high rolling hills in a semicircle behind it, Conachair, on the northern side, is faced with vertical rock cliffs up to high, which constitute the highest sea cliffs in the UK.
