There is only one proper thing to do when the sun shines in Alaska: polar bear dip!

After a morning of long paddles and sunny hikes, all the guests and crew of the Safari Endeavour gathered together on the Easy Dock to take the plunge into the 49-degree waters of Hallock Harbor.

Those who didn’t swim cheered and took photos from the decks. There were cannonballs, belly flops and dives. There were splashes, screaming, laughter and lots of shivering. The swimmers went in again and again. The hot tubs have never been so crowded as they were that evening.
