Experience a walk along the restored Al Aqr Wall, a true hidden gem in Nizwa. For a small fee, you can ascend these ancient mud-brick fortifications for incredible panoramic views over the old city, lush date palms, and mountains. The best time to visit is just before sunset for magical golden light, and as dusk falls, the entire wall is beautifully illuminated, making for an unforgettable stroll through history.
