Borj Bolila is a coastal site in Libya featuring a combination of reef structures and underwater caverns. The topography includes archaeological remnants scattered across the seabed. Divers can explore depths reaching 20 metres, with entry facilitated directly from the shore. Conditions are generally mild, though the presence of caverns requires caution regarding overhead environments, and boat traffic is a noted hazard. The site supports a variety of Mediterranean marine life and invertebrates typical of the regional habitat. Suitable for beginners, the water temperature fluctuates between 17C in the cooler months and 27C during the summer.
