It’s a country that’s overlooked since UAE has skyscrapers or high rises while Oman doesn’t have that (since their focus is more on culture and maintaining the “old Arabia” look & vibe whilst being rich in their own way). I mean, you can look up travel content about the UAE and there’s tons of results while for Oman the amount of travel content is kind of sparse in comparison even though people do go there.
It’s kinda dusty, slow, traditional, car dependent. It doesn’t have much in the way of tourist infrastructure/fun things to do. Even if all you want is to sit on the beach, it doesn’t have traditional beach boardwalks/towns like you could get…everywhere else.
