Description The Edge of the World (Jebel Fihrayn) is an unexpected and dramatic geological wonder in the rocky desert northwest of Riyadh, Saudi Arabia. The site earned its nickname because from atop the escarpment, you have an uninterrupted view of the horizon. Its part of the much longer Tuwaiq Escarpment, and drops down 1,000 feet into an ancient ocean bed. While standing on the cliffs, youll spot dried rivers weaving across the land, and see camels moving far below.
