You can try Zikreet. It's on the way to Dukhan.

Get on the Dukhan Road ... and go straight, straight, straight ... there's a little detour happening at the moment at Shahaniya ... but it's signposted ....

Eventually you will see a flyover. Just after the Zikreet shops on the left hand side.
Turn right at this flyover (Arab School on the corner) ...

Follow road down and then explore ...

This is a beautiful piece of coastline you can get by without a 4 wheel drive, but having one is certainly better as you can access more places.

The water here is beautiful.
