Al Baida, Petra
Al Baida is the semi-desert area which lies well outside the main Petra site. To get there you take the road which goes through the B'dul village of Umm Sayhoun.
The B'dul have rights to pitch their tents anywhere in the area other than the edges of the main road, which are usually farmed by Wadi Musa villagers. The Ammarin tribe (also Bedouin) have lands further north in Al Baida, and thus further away from Petra itself. The B'dul are primarily involved with tourism, the Ammarin much less so, although they do run at least one tourist camp.
Al Baida is excellent for hiking and walking, though you should organise a local guide to go with you. It's a more fertile area than one might expect: there are a surprising number of trees as well as small fields which grow wheat and vegetables. And there are, of course, goats and sheep everywhere.
I loved the rounded, pale-yellow rock outcrops in this area. Many of their caves have been converted into dwellings, in the distant past or far more recently, and there is one very large outcrop between Wadi Musa and Umm Sayhoun which is a full village, with villagers (B'dul, I believe) living in multiple caves as well as their tents.
As you drive along the road you'll spot many a cave-dwelling with a Bedouin tent outside, a herd of goats (sometimes sheep) wandering, a campfire.... and a trusty truck parked nearby.
If I'd had time I would have liked to explore this area much more (with a guide, of course). If you have time I suggest you do so too.
You can also go and visit the desert in this area, there are many canyons and interesting places & sites around but don't go on your own, you might get lost so be sure you have a guide and you know where you are going.
Baida is a most wonderful place for hiking! But there are no maps, no signposts, no "authorized tracks".
In other words, you would be most unwise to come here without a guide - and an experienced trekking guide at that! Get yourselves together and six or ten of you hire a guide for a day's trekking, it will be a day to remember.
Baida is a semi desert area to the north of Petra. it stretches from the hills of Shobuk down to Wadi Araba.
It is a beautiful area, and many of the local people like to come here to rest, to walk around or to picnic with their families. Often the guides bring tourists here to an evening cookout.
The word "Baida" means "white" in Arabic, and the rocks and sand in Baida are in fact mostly white. In this the area is unlike Petra, and also unlike Wadi Rum.
The area is a rocky one and in many places you can see much the same sort of formation of rocks as at Wadi Rum. It lacks only a little, perhaps the colours of the sand and the rocks, to be as beautiful as Wadi Rum, but also has the attraction of views and roads down to the Rift Valley of Wadi Araba.
