Luxor is approximately 700 kms from Cairo and you can take flight, government or private train or cab from Cairo to Luxor. Costs of various means keep changing, so, check the internet for best prices. You can easily get good hotels at reasonable prices in Luxor.
Best means to reach Karnak is hiring a cab from your hotel. However, you can also opt for microbus from the bus station. You can also opt for local organised tours.
The Karnak Temple Complex, commonly known as Karnak, comprises a vast mix of decayed temples, chapels, pylons, and other buildings near Luxor, in Egypt. Construction at the complex began during the reign of Senusret I in the Middle Kingdom and continued into the Ptolemaic period, although most of the extant buildings date from the New Kingdom.
