For today, I had booked a tour through my hostel for the visit to Giza. This trip included a private car ride to Saqqara, Memphis and Giza pyramid field for 25 USD. The tickets at places and tours/camel rides are extra. To be honest, everything in Egypt is quoted at a much higher price than it should be. People are always trying to con you for stuff. All the tour taxi drivers will take you to random souvenir outlets where you will end up overpaying for stuff. First of all, if you get an Uber to each of the three places, you will end up paying much less than the 25 USD. On the other hand, wait times could be high and it is possible that you will find it difficult to get an onwards Uber from there. All the three places are pretty far from each other. I thought the 25 USD was a good deal for the taxi.
At Saqqara I paid 120egp for the ticket and then inside you can hire a guide. I negotiated and got one for 150egp and a horse ride to the tombs close-by for another 100egp (the horse ride was a scam, you can easily walk it to these tombs). You can see the pyramids and a number of tombs and actually go inside one of the pyramids for free. The people are pushy towards selling their stuff everywhere in Egypt and "there is no free help" here, even if its something as simple as asking someone to click a photograph for you.
At memphis I went and saw a massive statue of King Ramses-the second and a lot of other statues. All these statues had been converted to an open air museum. The overall experience here was rather disappointing as Memphis was supposed to be where the kings once lived. None of that remains anymore. Again salesmen and people are extremely pushy. Don't buy souvenirs here; they are very over priced.
At the pyramids of Giza, after heavy negotiation, I took a large tour camel ride for 35 USD. It was a complete rip off. The people will try to sell you three different tours ( small, medium and large) and will start with ridiculous prices. Honestly, I hated this tour. The guide had no information on the pyramids itself and all he did was click great pictures. If that is what you want, then go for it. I would suggest not taking the camel ride unless you aren't okay with walking 3-4 kilometers. Walking is better and much cheaper. The entry is just 150egp and then you don't have to pay anything else unless you want to go inside one of the pyramids. Just be careful of people inside the pyramid complex. There are some major scams here. Don't buy anything and don't let people click pictures for you, they will ask for money later. Just go and do your own thing. I did not go inside the pyramid here because it was 350egp and there is nothing major to see inside.
Regarding tipping in Egypt, everyone will want a tip and they will never be happy. Stick to a standard 10-15 percent tip. You really don't have to tip everywhere unless you're happy with the service.
I got back to the hostel by 5pm and then ate a late lunch at Filfela which was also very close-by. They have great cheap shawarmas.
Later at night, I went to Khan el Khalili market to check out the vibe. Its open till midnight and night time is a good time to visit. Its a taxi ride away from Tahrir Square. Just Uber it everywhere in Cairo or at least know the Uber pricing before hiring a local taxi. Khan El Khalili has a complete bazaar feeling to it, with numerous shops displaying souvenirs, carpets and perfumes. Its good to just go and get lost in the market and enjoy the vibe. I did not try to buy anything from here. Things are always over priced at all these touristy places.
I took the night train at 12:15am the next day to Luxor. The train was a Spanish style seater train and was supposed to reach by about 10:30 am in the morning. I was the only Non-Egyptian on the train. Foreigners usually take the sleeper trains which are much more expensive. The ticket cost me 114egp as I had pre booked it online through the Egyptian railways portal. If you try and get the ticket at the station, they will probably try and sell you the sleeper train ticket. I think it was a very good decision, on my behalf, to pre-book the trains.
