There are many other interesting things to visit in the Negev Heights (Ramat Hanegev) region, such as oases (Ein Avdat, Ein Zik), the Large, Small and Ramon Craters, and the recently developed wine route, which is combining eco-tourism with boutique wineries, olive growing, and the cottage-industry production of goat cheese (all of which is pretty amazing in an arid desert region of approximately 300 sunny days per year, and only about 70mm of rain). This is a less-travelled part of Israel, but well worth the visit, either as a special trip or on your way south from the centre of the country to Eilat. The roads are excellent and there is a bus service approximately once an hour from Beer Sheva. Make sure you bring a hat, good walking shoes (not sandals) and plenty of drinking water. Camp sites are not as well equipped as in some other parts of the world, but there are excellent field schools (some with hostel accommodation) and bed & breakfasts in the area.
