This is a real "wow!" destination, only accessible by plane or boat and usually quiet enough to hear the ice cracking and popping. A UNESCO World Heritage Site, at 3.3 million acres this Biosphere Reserve is well worth a visit. From the moment you arrive you'll be greeted with towering mountains and rivers of glacial ice which run down the mountain valleys to form sheer cliffs of ice. If you are visiting by boat, one of the park rangers will join your ship at Bartlett Cove and they will stay with you as you explore – not only to provide fascinating insight into the park’s history, but to answer any questions you might have too.
The glaciers here are truly spectacular. Margerie Glacier is a wall of ice you can sail right up to, providing most visitors with an opportunity to watch the ice calving into the bay - even if it's just little chunks! Johns Hopkins glacier is around 12 miles long, Margerie 21 miles and Grand Pacific 25. These might just sound like impressive numbers but I promise you once you're there you'll be in absolute awe - it's then that the scale starts to sink in.
Look out for the orange beaked puffins, guillemots and murrelets who live in the area, and try and include a stop at South Marble Island to see the sea lion haul out.
Last but not least, keep your eyes open for whales – I had a really close encounter with a humpback whale here in 2016!
