Balqa, Zarqa, Madaba, and the southern region, which includes (Aqaba, Ma&#39;an, Tafila, and Karak).</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Each of these regions contains high mountainous areas, characterized by cold to very cold weather conditions in the winter and pleasant and moderate to relatively hot weather in the summer, and each region contains an area that is highest above sea level.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> In the North Region, the highest mountain peak is Umm al-Draj Mountain, which is 1,247 meters above sea level. It is located between the governorates of Jerash and Ajloun. In the Central Region, the highest mountain peak is the Tlaa al-Ali area, which ranges in height from 1,100 meters to 1,200 meters.

In the northern and western regions of the Kingdom, Umm al-Dami Mountain is located far from the centers of air depressions, and the cold masses weaken as we head south.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Umm al-Dami Mountain is considered the ideal choice for climbing enthusiasts. It takes approximately two hours to climb. The mountain also includes an astronomical observatory to introduce tourists to the image of the sky, the constellations, stars, celestial constellations, and others.</p>
