Hit these 400-year-old coral walls before 10am to dodge the brutal coastal heat. You only need 90 minutes to scout the rusting cannons and Omani artifacts, but the surrounding Old Town alleys are the real highlight. Skip the overpriced souvenirs inside the gates and grab fresh street food nearby instead. Definitely splurge on the top-rated $50 guided walking tour; it makes the history actually stick instead of just staring at empty stone cells.
