The north-west arm of Beagle Channel offers a prime opportunity to learn about geology, glaciology and nature's splendour. This place is known as Glacier Alley and with good reason: an endless chain of majestic glaciers line the waters, leaving awed observers reluctant to look away, lest they miss out. España, Romanche, Alemania, Italia, Francia, Holanda: it's hard to decide which of these ice giants is the most spectacular. Their wild might is sure to impress you.
