Tracy Arm is a fjord in Alaska, close (72 km) to Juneau. It’s named after Benjamin Franklin Tracy, a general from the Civil War. It’s a deep and narrow fjord of 48 km long in Tongass National Forest. A fifth of it is covered with ice.
At the end of Tracy Arm lay what they call the ‘Twin Sawyer Glaciers’, North Sawyer and South Sawyer. You can spot black and brown bears, sea lions, seals, mooses, wolves, birds and mountain goats there.
At Tracy Arm you don’t dock with the Disney Wonder. The ship cruises through the fjord the whole day to the glacier to turn there and return. Depending on the time of the year you go through a bunch of ice rocks. You see those breaking off of the glacier at certain moments. On board there’s breakfast on deck for the early risers and barbecue for lunch. All the entertainment happens on deck so everyone (also the kids) can enjoy the view.
