12 hour tour from Tel Aviv (3.5 hours on-road):
Once past Jerusalem, we head for the desert. Although this toure is explanations intensive (no time for translations), we do get a few chances to shortly track 4x4 into the Judea desert. On our way to the sugar cane path, used long before, by John the Baptist and Jesus, or the Samaria overlook view point or the Judea desert Horkaniya vally view point.  The 4x4 track views  typical Judea desert geology, learning about the turbulent times leading to the 2000 years exile of the Hebrew people from the Home-Land.

Further down in the lowest point on earth, rests the 50 k"m long turquoise Dead Sea.  Contrary to its name, it attracts tourists and Israelis all year round. This is for two sensational qualities. One is the "walking on water" experience enabled by the remarkably heavy water and second, is the miraculous healing quality of the water, sulfur springs and UV-B sun rays, known for their  successful combat of the most stubborn psoriasis skin irritation!

Masada (option A) ! Deep down in the Judea desert, on an isolated table mountain, are ruins nearly 2000 years old. They are a growing monument to the free spirit of the human race. They are a silent  heroic evidence of the resistance demonstrated by 930 men, woman and children against tens of thousands of trained Roman soldiers. This was chosen by the UN as a world heritage site , saluting freedom of choice and spirit! The visit on the mountain is preceded by a short explanatory video.

Note: 
1. Masada entrance fee is about 80 NIS per person (including two way cable car).
2. Temperature on Masada in June-July-August could be around 42 deg C. / 105 der F. Not recommended under 16.
Alternative tour: North Judea desert to Dead Sea. 

Ein Gedi oasis nature reserve (option B). This is the most enjoyable Judea desert oasis water track. With a few waterfalls, shade and many times, Ibex walking not far away. In summer, it is a real treat!

Note:  Ein Gedi entrance fee is about 29 NIS per person.
