Egypt has a wealth of places of interest for you to visit and you could easily fill a few weeks doing a different activity every day. Egypt is most famous for its historical buildings and structures such as the Pyramids and Pharaohs tombs, but there is so much more to do that some people simply are not aware of and often end up on missing out.
If you like to explore then why not book a jeep safari or do it yourself on quad bikes. These safaris will often take you through desert land showing to local wildlife allowing you to get up close and personal to some magnificent creatures. If you are more of a water baby, then why not opt for a Dolphin safari trip. These are often done in areas such as Dolphin House which is notorious for Dolphin sight seeing and surrounded by a beautiful reef.
Many tour operators will allow you to book trips before you go or directly with them when there but if you are happy to wait then you may be able to book cheaper when you are there through a third party. If possible, try and read some reviews of the local companies offering these trips to get an idea of what to expect.
