Oh! You've been there 😮 I remember when me and my husband decided to go to Jebel Jais, he pinned the location but we didn't know what happened, I forgot what he used that time Waze or Google Maps, we lost in the rocky and rugged mountain of RAK and it was scary 😨 but thanks God we found our way back.
Yes, back roads are not well marked, but now it is much better in terms of phone signal.
True, no marking when you enter those rugged mountains. The site that we've reached has no signal it seems an isolated area.
