Well-labelled and atmospherically lit at night, the ancient ruins of Al Baleed belong to the 12th-century trading port of Zafar. Frankincense was shipped from here to India in exchange for spices. Little is known about the port’s demise, but the excellent on-site Museum of the Frankincense Land charts the area’s settlement since 2000 BC and illustrates the nation's maritime strength, including its recent renaissance. The site includes several kilometres of landscaped paths and the adjoining reed beds make for good birdwatching.
An electric vehicle (500 baisa per person) takes visitors on a 20-minute lap of the extensive grounds. There's also a handicrafts shop and cafe on site.
