In surrounding muscat visting places like Al khairan Beach - you will get on the way to jabal shifa Beach Road Clean and less populated. sinkhole - On the coastal road from Muscat to Sur we mad a stop at Sink Hole (Dibab Lake Park) as suggested Oman Offroad Explorer. We parked a car and walked on the short path which lead us to the sinkhole. Although we know what to expect, the view still amazed us. Water here is clear, you can swim, but it is quite salty, more than in the ocean but less than in the Dead Sea. Wadi Bani Whalid -http://omanexpat.blogspot.com/2007/02/wadi-bani-khalid.html
I have been in very nice place in Oman if somebody hear it HATT and BLAD SEAT it is really nice places on the high mountains so there is could weather and nice view from the top.
The good thing is the road but it is not complete to the BLAD SEAT so you can drive by small car till the end of the road, Around 35-45 Km with normal road and stop you in the high location so you can see from the top to the small village BLAD SEAT it is really far...
Some good info :-
- The way to that place from muscat to nizwa to al-hamrah to hatt and Blad seat... The same way to jable shams - There is a way to Rustaq from the same way it is very shortcut but you must need four wheel drive car. it is tough off road but you will have much adventure...I like it - At the end the best is to use manual gear!! becuase the manual gear is helps you to control the car much in the mountains
Quantab beach, Yeti beach, al shifa are good places to go in the weekend..
Yes as you said but I haven't been there yet. Try to visit some places in adakhlia like Nizwa,Bahla,Tanuf...etc. It's really quite place and very friendly people hope you have been there before. If not try to have the weekend there.
