The Dhayah landscape nomination mentions the lagoon, the palm gardens, a hill fort, tombs and mountain villages. The centre of it seems to be the fort on a 70m high hill, so this is where we headed. Luckily google maps sent us there on a weird unpaved road. Clearly not correct, but it gave us the best views of the fort. The fort itself is, as common in this area, completely reconstructed to a degree, it looks fake. It has a visitor centre with opening times (daily 08:00-19:00) and free entry.
From the top you are able to spot some of the other elements. The palm gardens with the falaj are set around the fort hill, but seems to be in commercial use and walled off. The lagoon is part of the modern city of Dhaya and we did not bother to go there. And of course, Dhayah also mentions old graves. Like Hatta, Faya, Mleiha and Shimal. You get the gist. According to the UNESCO website, four of these graves are planned to be made accessible by creating an Archaeological Park, I didn’t find anything about its existence so far. UAE seems to push this site for the near future, so it might become more interesting. The current visitor experience is not impressive.
