The main reason to visit Hail is because it's a good base for exploring the extensive rock art site at Jubbah. But while you're here it's also worth exploring the city's pleasant souq close to the impressive Qishlah Fort, and one of the country's last remaining proper flea markets to the east of the city centre.
A historic crossroads of trade, especially during the hajj season when camel caravans passed through, Hail has played an intriguing role in the history of modern Saudi Arabia. It was the capital of the Al Rashid tribe, who at one point were the direct challengers to the Al Saud claim for regional power. While the Aarif Castle is one of the few reminders left of the Al Rashids, the much bigger Qishlah, built by King Abdul Aziz, is a reminder of who won.
