Waterfalls of Wadi Al Hoqain
Wadi Al Hoqain offers a picturesque drive and lots of nice picnic spots. For more adventures ones (not us this time), it has several hikes to turquoise pools. We will visit again.
Pros: picturesque drive, easy to access and follow, lots of nice picnic spots, close to Al Hazm fort which is one of the best forts to visit in Oman
Cons: too much rubbish, not sure where you can swim
