Whether you are watching the sun set over the gulf, scrambling over the ruins of Portuguese castle at hormoz or just dropping down several gears to the ultra-relaxed pace at which this part of the world operates , you can’t escape the fact the Persian gulf offers a different experience to the rest of Iran. There is geographical contrast- the coast and islands of the gulf itself- but the major difference comes from the variety of people who live here.
