By bus
Foreign travellers can get to Abu Simbel by coach or minibus from Aswan, travelling in police convoys. There is at least one daily convoy each way, taking 3 hours. Seats on the minibuses traveling in the convoy can be arranged at your hotel or through the Aswan tourist office. The cost for a return trip is 100LE. This does not include entrance fees, but may include travel to additional sights in Aswan such as the High Dam or unfinished obelisks. Make sure your minibus has air-conditioning.
Tip: Sit on the left hand side of the bus. You will see the sunrise in the morning if awake and be in the shade on the way back.
There are also two public buses from Aswan 3 hours each way - one that leaves at 4am and the second at 11am. All convoy buses need to leave for their return journey to Aswan by 4pm latest. Make sure you make the most of your little time in the temples.
