Originally built as an oceanographic research vessel, Un-Cruise’s upscale-but-rugged Safari Explorer takes adventure-seeking cruisers to hidden hideaways in Hawaii and Southeast Alaska. With a maximum capacity of 36 guests in 18 cabins, Safari Explorer has a low-key, homey ambience. The all-American crew prepares locally sourced meals paired with quality wines (included in the fare) and takes guests on thrill-inducing Zodiac rides, and kayaking and snorkeling excursions.
