Embark on a whale watching adventure to the historic Sentinel Island Lighthouse in a custom built luxury whale watching vessel. Relax in a heated cabin with outside viewing areas while spotting Humpback whales and other marine life. Upon arrival at the lighthouse, enjoy a short hike on a scenic boardwalk, explore the lighthouse that was built in 1902, and take in the views of the surrounding islands. Next, watch more marine wildlife while enroute to the harbor where your driver-guide will make one final stop at Brotherhood Bridge which offers a stunning view of the Mendenhall Glacier**, before you return to your ship.
