In short: Established in 1997, the Aqaba Marine Reserve represents Jordan’s commitment to preserving its only maritime outlet to the Red Sea. Despite occupying just a fraction of the country’s limited coastline, this protected area serves as a vital refuge for hundreds of unique species and was designated a UNESCO World Heritage Site in 2026.

The Aqaba Marine Reserve is a critical environmental hub located within Jordan’s Aqaba Governorate. Spanning 2.45 square kilometers, it protects a 7-kilometer stretch of coastline, which accounts for approximately 2.6% of Jordan’s total marine territory. The reserve extends 350 meters seaward and 50 meters inland, creating a controlled zone designed to mitigate the pressures of intense economic and tourist activity along the country’s 27-kilometer maritime border. By securing this area, Jordan aligns itself with international conservation standards set by the International Union for Conservation of Nature.

The biodiversity within these waters is remarkable, particularly given the arid climate where annual rainfall averages only 30 mm and summer temperatures can climb to 50°C. The reserve supports a complex web of life, including 157 species of hard corals, 72 species of sponges, and 645 species of mollusks. It is also a sanctuary for three species of turtles, most notably the hawksbill sea turtle, and provides a habitat for two endangered types of giant clams. The presence of three distinct seagrass beds further bolsters the area's ecological stability, offering essential support for the diverse marine life found here.

Fish diversity is a defining characteristic of the reserve, with 507 species recorded within its boundaries. These populations thrive among coral reefs that sit remarkably close to the shore, stretching over a distance of 13 kilometers. Beyond the underwater flora and fauna, the reserve is a significant site for avian life, hosting numerous waterbirds such as gulls, terns, and skuas. This concentration of life in such a small, climate-stressed region highlights the importance of the reserve as a biological anchor for the Gulf of Aqaba, ensuring that Jordan’s limited access to the Red Sea remains a thriving, protected environment for future generations.
