Mt. Katharina is the highest mountain in Egypt at 2642 metres, with a small Orthodox church on the summit. According to tradition this is the place where monks, after a dream, found the missing body of the martyred St. Katherina. Jebel Musa (Mt. Sinai) is below, and the views onto it and the whole high mountain area are stunning. It is a tough 3-4 hours climb, but very worth the effort. Mt. Katharina is usually approached from Wadi Arbain and it could be climbed in one single day, but several other routes exist and doing it overnight is recommended.
Other names/spellings: Mt., Mount, Jabal, Gebel, Gabal, Djebel, Djabal – Katherina, Katherine, Katarina, Katrina, Katerina, Catherina, Catherine
