Review of Viking Osiris deck 4 (Bridge-Pool-Lounge)
The fore-located Navigation Bridge (called "Wheelhouse" on riverboats) is accessible to passengers.
The ship's swimming pool is located aft. Its sunbathing area is furnished with padded sunloungers and adjacent to the Aquavit Terrace - shaded seating area (outdoor lounge) with comfortable sofas and 4-seat tables.
Forward on Pool Deck is the ship's Bar Lounge connected (via glass doors) with an open-air Promenade - an outdoor viewing area (at the boat's bow).
One Lift (passenger elevator) connects all cabin decks. All decks are interconnected via stairs (forward, midship, and aft stairways).
