Dendera Temple, Luxor
Concierge.com's insider take:
If you have a free day and are not already booked on a Nile cruise, consider a day trip by boat to Dendera Temple, a Greco-Roman complex dedicated to the goddess Hathor. This day trip sails north of Luxor just past the Qina River bend. The vessel, the Royal Lotus, is a former cruise boat converted into a floating restaurant and carries about 90 passengers. The fare, around $80, includes breakfast, lunch and dinner as well as a guided tour of the temple complex. There are sunchairs on deck; the river scenery alone is worth the trip.
