Menorca (or Minorca) is one of Spain’s Balearic islands in the Mediterranean Sea. Traditionally more low-key than its neighbors, Mallorca and Ibiza, it’s known for its endless beaches, from miles-long sandy crescents to rocky, turquoise-watered bays called “calas.” Pine trees fringe the coast. The capital, Mahon, is on a bluff overlooking a large harbor, with Georgian mansions and a church with 13th-century roots.
