Qeshm Island
Situated in the Persian Gulf just south of the port city Bandar Abbas, Qeshm is famed for its unspoilt natural beauty and diversity. The largest island in the Persian Gulf, Qeshm boasts some particularly impressive geological features: the Namakdan salt caves, for example, are reportedly the longest of their kind in the world. The intriguing erosions of the Chahkouh Valley are also worth a visit, if only for the eerie, post-apocalyptic ambiance they provide.
