The Nabataeans built and inhabited Avdat from the 1st century, until an earthquake deconstructed the structures early in the 7th century. Truly magnificent Nabatean fortress with layers of ancient history. Fantastic stop for history buffs, with sweeping views over the desert mountains. It is indeed quite incredible to find water channels in the middle of the desert, but just the same as around the dead sea, there are plenty of springs in the the Negev. The best to go there autumn to winter when the weather is just fine.
The hike to the top is definitely challenging, so be sure to take it slow and steady. The views of the canyon at the top are just spectacular, making the trek well worth it. Very interesting archeological site. Those anchient Naabatiens were crazy dudes, making wine in the middle of the desert. The site is well maintained and very interesting. It can get very hot/cold so try to visit during transitional seasons.
