Immerse yourself in the hidden world beneath Alaskan waters. Glide though eel grass beds, drift through giant kelp forests and explore rich, rocky shoals in comfortable style aboard Alaska's original semi-submersible tour vessel. Thanks to long hours of summer daylight and the nutrient-rich currents of the North Pacific, you will discover that the cold waters of Alaska team with life, including a variety of aquatic plants, jellyfish, anemones, crab, starfish and fish. Large, underwater viewing windows allow you to encounter the underwater world up close while the narration of a trained naturalist enhances the experience. A scuba diver using underwater video and onboard monitors reveal even more of the world beneath the sea. The divers bring fish feed with them to bring the fish right up to the windows. Your tour will conclude above deck with refreshments, including cookies topped with kelp marmalade. An open-top aquarium contains sea creatures right on board the vessel, a great opportunity for hands on exploration and photographs. You'll be returning through Sitka Channel, a sheltered waterway that is the heart of Sitka with its fleet of fishing vessels, float planes, and bustling waterfront. This heated, restroom-equipped vessel delivers an underwater tour very different from those in other parts of the world. You will experience life beneath the waves like you have never seen it before.
