Karnak temple is the highlight of any trip to Luxor. The sheer span of the temple can leave one breathless. The temple was built by many pharos over the span of 300 years. As move from the inside of the temple to outside, you can walk thru time, the inside being the oldest part of the temple. You can get lost in the Hypostyle Hall's 134 columns, walk on the avenue of Spinxs and admire the size of the Obelisk of Hatshepsut, the tallest obelisk left in Egypt. No visit to Karnak temple can be complete without attending the light and sound show at night.
