Come to Norway to see the fjords.
What’s a fjord?
Here’s the brief answer:
Geologically, a fjord or fiord is a long, narrow inlet with steep sides or cliffs, created by glacial erosion.
The steep sides of the cliffs decend straight down to the seabed.
The sea is quite deep, deep enough for a large cruise ship.
The fjord is so narrow that the sides of the cliff pass ever so close to the side of the ship - close enough to almost reach out and touch them.
The remarkable moment comes when, in this narrow channel, the cruise ship stops near the end of the fjord, turns one hundred and eighty degrees and returns to the open sea.
