(Lonely Planet) -- The romance of long ocean and river voyages of history holds powerful sway over the dreams of many world travelers. But there's no need to relegate the great voyage to the realm of books and dreams -- many can still be done today in classic style.
The following ocean and river voyages rank among the most iconic and memorable travel experiences on or off water. So put on your best Poirot accent, and brush up on your Huck Finn river lingo, and climb aboard for the voyages of a lifetime.
1. The Nile
Sailing boat or time machine? The world's longest river feels like it's the oldest, and to board a vessel on the Nile is to peel back millennia and slow down to river speed as ancient temples, oxcarts and palm trees -- unaltered since Pharaohs ruled the roost -- pass by.
