The pyramids don't look that far from the road, but they're actually are really far, they're just wicked big so they look closer than they actually are. The camel tours are expensive, but worth it!
If you are a horse riding lover visit FB Stables and Ride in the shadow of the Great Pyramids or further afield on a half day trip to Saqqara or Abu Sir or camp out over night with a barbecue and fire
