Sailing a Blue-Green Sea: Cruise ships have long been accused of having a rather unfriendly attitude toward the planet… Today, however, many of the cruise lines have been shamed into mending those bad habits, and some are going above and beyond what the law requires. AdventureSmith Explorations offsets all of the carbon emissions that result from its cruises.
Our Pick: This company offers its carbon emissions and focuses on learning and adventure cruises in Southeast Alaska aboard its fleet of small boats, which range from intimate charters (accommodating just 12 people) to large cruisers that can take around 100 people. The boats have kayaks and small skiffs for the numerous excursions that include eveything from kayaking in Glacier Bay National Park to wildlife watching near Tracy Arm, the ABC Islands, Icy Straight, Misty Fjords and Frederick Sound. Most trips depart from Juneau.
