Dubbed the ‘Grand Canyon of Arabia,’ the Mountain of the Sun or Jebel Shams as referred to by the locals provides adventure seekers the perfect opportunity to go rock climbing and hiking. Believed to be the 1st place in Oman where the sun rises, Jebel Shams is the highest point in the Al Hajar Mountain Range and is found some 240 km from Muscat. Though, complete with two summits, members of the general public are only permitted to scale the southern mountain for the northern one contains a military base. While catching the sunrise is the main highlight, the vistas of nearby villages and towns will leave you overwhelmed.
