Welcome to Red Sea Coast
At the time of research, this was the least developed stretch of the Red Sea in the entire Kingdom, with much of it (especially south of Haql) literally just desert meandering into the sea, complete with camels that can often be seen basking in the sun on empty beaches.
This situation is about to change though, as stretches of this barren coastline will soon be developed beyond recognition. The beginnings of this are already apparent south of Haql, where efforts to turn coral islands like Al Wasl into Dubai-style resorts have begun. Fortunately, there is enough coastline that whatever changes loom, you should still be able to find your own isolated spot for quite some time yet.
