Namaste !
I have been to Diu in last year December by road. It was a week trip. Started from delhi to Gujarat, then Dwarika, visited most popular place dwarika dish temple & bhet dwarika.
After this drive till the most beautiful temple Somnath near to sea. Very peaceful & attractive.
Next day started from somnath till DIU island a most wonderful & peaceful place. Enjoyed so much.
Very adventurous place. Did water sports.
Must visit : -)
