What can be more adventures than sailing through “the old world” and seeing the magnificent temples at Esna, Edfu and Kom Ombo. If you have the time and resources, spend it on a 12+ day’s journey and visit El Amarna, Sohag, Cairo, Tuna El-Gabal and Ashmunein.
12. The Brahmaputra – China, India, Bangladesh
From the Angsi Glacier in Tibet, through Arunachal Pradesh in India and all the way south into Bangladesh.
