Post this, I started from Hatta towards Sohar in Oman, We drove around 70kms and trekked the last 10-12 Kms through the desert till we reached the Oman border . I am not really sure about an on-arrival visa but since I already had an Oman tourist visa, it was pretty hassle-free for me to cross the desert border.. Also make sure you carry Omani Riyals because I couldn’t see any exchange counter nearby. An Omani Riyal costs like 173 INR.
