SouthSinai is safe and peaceful. That means from Taba - Nuweiba - Dahab to Sharm-el-Sheikh and the region of St. Catherine is open to travel. Desert trips can be done, no incidents have happened recently. The warnings of most of the foreign ministerys are wrong, they do not differenciate between North- and SouthSinai. None of the Europeans who live in Nuweiba or Dahab have left Egypt of security reason.
At the moment it is not allowed for Europeans to travel from Cairo - Suez - Nakhil - Taba to Nuweiba with the East-Delta-Bus. Unfortunately they have to travel from Cairo via Sharm - Dahab to Nuweiba, but the Bus is more omfortable.
