Frederick Sound is an 80 mile long body of water that runs east to west through the heart of Alaska's beautiful Inside Passage from its Stikine River delta eastern origin to its western junction with Chatham Strait. Its incredibly rich marine environment supports an amazing diversity of marine life including a vast number of humpback whales numbering in the many hundreds which gorge themselves on an extraordinary abundance of krill and herring throughout the summer and late fall months through most of December. The protected typically calm summer waters coupled with the sheer magnitude of whales displaying their amazing array of feeding behaviors make Frederick Sound one of the worlds premier locations to observe humpback whales.

There are a number of wonderful bays and fjords found along this shimmering jewel including Leconte Bay with LeConte Glacier at its terminus. LeConte Glacier is the southern ost tidewater glacier in the northern hemisphere and recognized as the 'fastest moving ice' on the planet. It's a very active glacier frequently calving ice bergs into the fjord making boat navigation through the 6 mile fjord a challenge.

The abundant waters of Frederick Sound support diverse commercial seafood catches much of which is delivered and processed in the nearby quaint Norwegian fishing town of Petersburg. Other inhabitants frequently observed in this stunning remote wilderness waterway include healthy populations of Steller sea lion, Dall's porpoise, harbor porpoise and harbor seals. Black and brown bears, Sitka black tailed deer and wolves are not uncommon to see along its shorelines.
