Dear friends!
I can report back that the gates at the entrance of the Liwa Crossing are still wide open.
The route as described on the visitabudhabi site (https://visitabudhabi.ae/en/things-to-do/desert-and-outdoor-activities/off-road-desert-driving) is very doable for a self drive adventure with a group of friends.
There is a small section around 22.83639, 53.85700 where it may be tricky to get accross.
Enjoy the adventure!
Thanks @Emanuel and the Carnity team for a great morning out! Enjoyed sweeping at the back and getting the chance to snap a pic or 2.
See you all soon on the sand!
