No need for 4 wheels. Road there is quite smooth. I drove corolla from downtown to sinkhole without any problem.

Not exactly sure but like most parks probably before Dusk , to be safe I’d try to get there before 4 pm . Remember though depending on the time of year and the temp plus the fact that this place is probably 300 yds below the surface it could be dark and cool or sunny and warm waters depending if the sun is overhead. The place to see is obviously the wadi which is about 10mins by car from this place

I’m not sure. It is a city park, so I would assume standard hours — 8 or 9 am.

I would wear a t-shirt at the sinkhole and then swim in swimwear. At the wadi, either is fine, just make sure you are comfortable and take reef shoes if you can as the rocks are harsh on your feet.

Is it open now a days?

Also public toilet facility available. Also one security post also there. But it is recommended you to not try to jump from the edges and trying to play if you are not an expert swimmer. Overall you can enjoy with your family.

Sorry, i was on vacation and travelling. I have never heard this dry. Near to the sea and there should be water. Wadi shab, bibi mariyam tomb at qalhat. Sea is beautiful colored all over this coast. sur has a few attractions worth visitting

No the sink hole site accessed by a normal saloon car and the there are excellent paved roads to reach the site . Hence you will not get an offroad experience
