Philae Temple, High Dam & Unfinished Obelisk Tour in Aswan

Your guide collects you from your hotel lobby or the gangway of your Nile cruise ship in Aswan, and you set off in a private air-conditioned vehicle. The three sites on this tour all lie south of the city center, along the stretch of river where the Nile breaks over granite outcrops and the old First Cataract once made navigation treacherous. That geology is the thread running through the day: hard pink and gray granite that the pharaohs quarried for statues and obelisks, and that 20th-century engineers anchored a dam against.

Aswan sits close to the Tropic of Cancer and is often the hottest stop on any Egypt itinerary, so pack with that in mind. Bring a wide-brimmed hat, sunglasses, high-SPF sunscreen, and plenty of water, and wear light, loose clothing with comfortable walking shoes. A small amount of cash in local currency is useful for tips, including one for the boat captain at Philae.

If you are joining from a cruise, let your guide know the ship's departure or meal times so the drop-off fits around them. Entry tickets for Philae and the Unfinished Obelisk are not included, so plan to cover those on the day.

Philae is one of the few temples in Egypt you approach across open water, and the short boat ride is part of the experience. The temple rises from its island in pale sandstone, ringed by granite boulders and palms, and the first sight of its colonnades from the water is the image that has drawn painters and photographers for two centuries.

The sanctuary belonged to Isis, mother of Horus and one of the most widely worshipped goddesses of the ancient world. Most of what you see was built under the Ptolemies and decorated further by Roman emperors, so Egyptian pylons and reliefs stand beside Roman-era additions. Look for Trajan's Kiosk, an elegant open pavilion on the water's edge, and the long colonnades of the outer court. Worship of Isis continued here long after it had ended elsewhere, and Philae holds some of the very last hieroglyphic inscriptions ever carved.

The temple you visit no longer stands on its original island. After earlier dams left it partly submerged for much of the year, it was dismantled stone by stone and rebuilt on higher ground on a neighboring island, part of the international UNESCO rescue campaign for Nubia's monuments. Your guide will point out how carefully the original layout was reproduced.

From Philae, you drive a short distance to the Aswan High Dam, completed in 1970 and one of the largest engineering projects of its century. It is not beautiful in the way a temple is beautiful, but standing on top of it explains modern Egypt as well as any museum could.

For thousands of years, life in Egypt depended on the Nile's annual flood: too little water meant famine, too much meant destruction. The High Dam ended that cycle. It holds back the river to form Lake Nasser, one of the largest artificial lakes in the world, which stretches south for hundreds of kilometers into Sudan. It regulates the water reaching the farms of the valley and the delta, and its turbines generate a substantial share of the country's electricity.

The dam also came at a cost, and your guide will explain both sides. The rising lake flooded the homeland of the Nubian people, who were resettled, and it threatened dozens of ancient monuments, including Philae and Abu Simbel, which had to be moved. From the crest you can look south across the open water of the lake and north toward the river and the city, and see the scale of the change in a single turn of your head.

The final stop takes you into the ancient granite quarries on the edge of Aswan, where the Unfinished Obelisk still lies in the bedrock. It is believed to have been commissioned by Queen Hatshepsut, and had it been finished, it would have been the largest obelisk ever raised in ancient Egypt, at roughly 42 meters long and well over a thousand tons.

The work stopped when a crack opened in the stone, and you can see that fault clearly. What makes the site special is everything else the stonecutters left behind. Along the sides of the obelisk, the trenches where workers pounded the granite with balls of harder dolerite are still visible, along with the marks of their progress. Your guide will explain how blocks of this size were separated, shaped, and floated downstream on the Nile, a process that is far easier to grasp here than from any book.

A walkway leads around the quarry, with steps and uneven rock in places, and there is almost no shade, so keep your hat and water handy. After the visit, your guide returns you to your hotel or Nile cruise ship in the air-conditioned vehicle.
