While most massive cruise liners are sailing across the open seas, True North Adventure Cruises are taking their passengers through shallow rivers to get up close to the coastal wilderness. Their flagship voyage travels to Australia's Kimberley region, getting guests unparalleled access to King George Falls, Montgomery Reef, and the Horizontal Waterfalls. To take advantage of the ever-present views, vessels are fitted with a sundeck and a forward observation lounge while dining rooms feature panoramic windows to display the scenery. Off the boat, their itinerary goes beyond tours and snorkeling and leans more toward hiking to ancient rock art, visiting the wreck of the Koolama, and having a heli-picnic at Eagle Falls. If cozying up to a Komodo dragon or sitting in on a crocodile initiation ceremony is more up your alley, True North also offers trips to the Indonesian Archipelago, Papua New Guinea, and Western Australia.
