I am assuming you mean in light of the recent unrest?
I was there last weekend - Muscat - and felt perfectly safe. Friends were camping near the Dubai border and again no problems.
Another friend was driving in Sohar when the unrest was happening and didnt even realise. over 9 years ago
there's definitely pressure on the Sultan of Oman to democratise, and the "Egypt effect" is certainly in evidence there. But the Sultan has so far responded with acquiescence and promises of reform. It seems he's seen the writing on the wall and has wisely opted to accept change rather than go down the blood-soaked path that Bahrain appears to have chosen.
But protests do still continue: on Wednesday this week 400 private security guards at Muscat international airport went on strike demanding pay rises. They blocked the main road to the airport and many passengers missed their flights. It certainly WASN'T a running battle with tear gas and rock-throwing, more like a strike you see in Greece all the time!
The day before there were several hundred state petroleum workers protesting outside the agency headquarters in Muscat. Again, noisy but not violent.
The chief of Oman's trade union movement has called on protesters to be non-violent.
Exercise caution while you're in Sohar, Ibri, Dhank, Shalalah and Muscat. The protests are almost always outside government offices, so try to find where they are and stay away. If you see a large pubic gathering, walk the other way.
personally I'd wait a while before going to Oman if I could, until the whole region has settled somewhat. But each and everyone of us has a different risk profile, and you have to decide what you find acceptable.
Just check your government travel advice and I'd also check your insurance policy really carefully to make sure you're covered in the event it does get ugly. I'd also check with your travel provider (if you're using one) about their cancellation policy and what security measures they're taking.
