Cairo is an incredible city with a ton to offer. The city is one of the largest in the world with a population of approximately 25 million! The main attraction of course is the great pyramids of Giza however, the city has much more to offer! Within Cairo you can find some awesome hotels from the Hilton to the Ritz-Carlton. The city also has uber which is great for visitors from the U.S. I would highly recommend downloading Uber, it's significantly cheaper than taxis, more efficient, and you don't have to worry about the hassle of having egyptian pounds. Speaking of egyptian pounds, you should be able to exchange egyptian pounds in the airport at one of the national banks. I would normally recommend against exchanging money in the airport because they won't give you the best rates, however the Cairo airport has the National Bank and they will offer you a rate close to the actual exchange rate. We ended up losing only about 2 dollars on a 250 dollar exchange. This was great considering most places will take a large commission or offer you a rate where you lose more. In addition, some people will accept dollars whether paying for tours or bartering in the markets. United States Dollars are highly sought after in egypt so keep that in mind when exchanging/ bartering and demand the market rate or extremely close to it. Moving on, you should definitely Egyptian Museum. They have everything from ancient hieroglyphics to mummies that were unearthed. I would definitely recommend paying extra to look at the mummies it is worth it. Also if you're a student or have a student ID you should bring your student ID because they give you entrance to most museums for half price. If you'd like, you can arrange a tour online or try to get one outside the museums just remember to barter and never accept the price they first give you. I would recommend a tour looking back, the museums in Cairo don't contain a great deal of explanation so you may just be looking at a lot of different artifacts and not understanding the historical significance behind them. Moving on, you should dedicate an entire day to looking at the pyramids. The drive is about 30 minutes and not bad at all. Make sure to bring significant cash to the pyramids because the entire access pass is 600 EGP. I would recommend doing this opposed to the other options. You're able to go into the pyramids, sphynx, and see the boat they used to transport material for the pyramid. Be wary when you walk into the pyramids, several people will try to approach you selling stuff and others will come with a badge claiming they work at the pyramids when they actually don't. They'll show you around the entrances and start telling you stuff and then demand money from you so don't fall into this trap (like we did). In addition, if you want to ride camels that's available, however don't pay anything more than 1/3 the price they offer. They'll ask you for an exorbitant price once you're on the camel, you just have to be firm. You could also probably look online for camel tours and find comparable prices and not deal with the hassle. Enjoy the pyramids just be wary of people showing you around and asking you for money, It's very unclear who actually works there and who is just trying to get your money. In addition to the pyramids you should check out the Bazaar's. These are the local markets where you can find everything from jewelry to hibiscus tea. I would recommend offering 1/2 to 1/4 of the price they first state depending on the item.  Khan-El Khalili is the largest bazaar and is located in the heart of old Cairo so you can also check out some of Cairo's oldest mosques like Al-Azhar which is across the street. As far as food goes, Cairo has a lot of great food to offer. I highly recommend going to Kaber Sobhy in Cairo. This is a very popular restaurant, the staff was incredibly friendly and the food was probably the best we had on the trip. Listen to the waiter's recommendations and go with what looks best. You won't be disappointed. Overall, Cairo is an amazing place with warm welcoming people that love to talk to Americans. If you can try to spend at least 3 days here to experience everything.
