The Hajar Mountains are a mountain range located in the eastern part of the Arabian Peninsula, primarily in Oman and the United Arab Emirates. They stretch approximately 700 kilometers and are known for their rugged terrain, deep valleys, and unique geological formations. The mountains are rich in biodiversity and host various plant and animal species adapted to the arid climate. The highest peak in the Hajar Mountains is Jebel Shams, which rises to about 3,009 meters. This region is popular for outdoor activities such as hiking, rock climbing, and exploring traditional villages. The mountains also play a significant role in the local culture and history of the surrounding communities.
