We visited the Abu Simbel in Egypt.
Abu Simbel is around 290 kms from Aswan. You can take flight from Aswan to Abu Simbel and back. Buses from Abu Simbel airport to Abu Simbel temple are free or you can book luxury boat cruise from Aswan to Abu Simbel and back which takes around 4-5 days.
However, the best way to reach Abu Simbel is book organised tour with local tour operators or book your own cab to take you to Abu Simbel and back.
The Abu Simbel temples are two massive rock temples at Abu Simbel, a village in Nubia, Upper Egypt, near the border with Sudan. The complex is part of the UNESCO World Heritage Site known as the "Nubian Monuments",which run from Abu Simbel downriver to Philae (near Aswan). The twin temples were originally carved out of the mountainside in the 13th century BC, during the 19th dynasty reign of the Pharaoh Ramesses II. They serve as a lasting monument to the king and his queen Nefertari, and commemorate his victory at the Battle of Kadesh.
