As i have now visited Oman for the second year in a row, i wanted to start this topic with describing the wadis and places i visited, and my experiences. There are lots of other wadis and things to see and do, but i will just mention the ones i visited and give a brief explanation on what they are about. Once you google the specific areas you will find hundreds of photos and more information. https://www.omantripper.com/ Above mentioned  site has really nice information on the topic.
