I took my 3 teenage boys to Snorkle Alaska. The operation is very professional, the staff were excellent and everything ran as advertised. I hate cruise ship shore excursions but THIS one, I recommend. Pick up at the ship and return. The wet suits fit snug with good reason. The water is cold but not as cold as you would think. Swimming in the kelp was a bucket list experience. My sons had a great time and still talk about 'snorkeling in Alaska'. Should I return to Ketchican, I would do this excursion twice. Forget the diamond and bamboo shirt stores, get into the ocean and swim! I have snorkeled all over the Carribean, but most importantly, I have snorkeled in Alaska!
