There's a fairly obvious main path through the siq, past the treasury that takes you down an ancient road, past an amphitheatre, hundreds of tombs and houses both grand and tiny. There's a huge variation in how well preserved the carvings are. Some of the buildings look as if they're only recently finished, with completely perfect carved details whereas others no longer have their façades and are only recognisable as hollows, without much indication of what they would've been used for.
There are camels and donkeys throughout the area as well as horses along the path nearest to the main entrance. Most of the animals are owned and looked after by local Bedouin people, who also guide them around and offer rides. This camel above looks like it has a wound on its face, I know there's also an animal hospital near to the reserve so hopefully the owner will get it treated.
