Mġiebaħ Bay is situated on the north-eastern fringe of Malta, approximately 14 kilometres (8.7 mi) from the capital Valletta and about 1.5 kilometres (0.93 mi) from the centre of Mellieħa village.[1] The bay lies at the foot of the Selmun peninsula, a promontory bounded by the Mġiebaħ Valley to the north-west and by steeper terrain to the east and south.[2] St Paul's Islands are visible from the bay, lying just off the north-eastern coast in the direction of St. Paul's Bay, which is situated approximately 2.5 kilometres (1.6 mi) to the south-east.
The beach itself extends for approximately 200 metres (660 ft) and features a mix of sand and pebbles, with coarser sediment concentrated on the eastern flank and dark yellow sandy deposits accumulating at the base of the coastal scarp in the backshore area[3]. The bay's northern headland is known as Ras il-Griebeġ.[2]The surrounding landscape is characterised by terraced farmland, rubble walls, and the dramatic contrast between limestone plateaux and clay-rich valley slopes.
