Cairo is a fascinating city to visit, with a cultural blend that can be quite different than what the typical western traveler is accustomed to. You can wander around grungy areas such as Old Cairo, or see visit new hotels and recreational areas around Gezira Island in the middle of the Nile River. You can encounter conservative and devout Muslims being called to prayer, or you can have a beer and see semi-clothed belly dancers at nightclub establishments. Most visitors like to take organized tours in Egypt, but you can get around independently with relative ease.
Visitors from most countries (including the USA) need to get a tourist visa before arriving into Egypt.
For some reason, the local Egyptian kids like to ask for pens as souvenirs from foreign travelers. I gave a young lad a pen I salvaged from a Montreal hotel, and he ran into his home as if I had handed him the mask of King Tut. Try to carry an extra pen or two and make a kid deliriously happy.
Some of the beautiful images of Cairo are courtesy of my good friend and frequent globetrotting travel companion, local Chicago architect Marius Ronnett.
Quick Tips:
One word you will get acquainted with in Cairo is "baksheesh". This is referring to small tips that are expected by locals for a variety of simple tasks and favors. Try to carry a stash of very small Egyptian bank notes for baksheesh.
You will encounter an endless stream of locals trying to do business with you. Whether they are pushing a restaurant, a hotel, or merchandise, these salesmen are very aggressive and persistent. Just try to be nice with them and they will eventually smile and give up. I can honestly say that because I am not a big shopper, these pesky guys are a real turnoff as far as my entering shops, so I bought very little in Cairo. However, some people may enjoy the challenge of bartering with these folks.
While most prices are listed in numbers, some local establishments may list items in Arabic numerals. For example, the "zero" looks like a dot, and the "5" looks like an "0". Even if you do not learn any Arabic words, try to memorize the Arabic numbers so that you will not succumb to a bad deal at a store.
Best Way To Get Around:
The vehicle traffic in Cairo can be extremely intimidating. It takes a bit of time to get accustomed to the rhythm of the traffic movements when you are trying to walk (or run) across intersections.
The Underground Metro system is not bad, but it only has one line. You may not have to use it too much, as many of the main sites in town are walkable. The best way to get to the airport is via taxi (I did get a free pickup from the airport because I took Salah Muhammad's tour, see "Memphis-Saqqara-Giza Tour" section below).
