The fore-located Navigation Bridge (called “Wheelhouse” on riverboats) is unusually large for European river cruise ships (extending all the ship's beam/width - from portside to starboard). The Wheelhouse is passenger accessible but non-telescopic (can't be lowered).
Next is the swimming pool with a surrounding sunbathing area with loungers and deckchairs.
Sonnendeck (Sun Deck) is a small shaded seating area covered by a retractable awning that is lowered when the riverboat passes under low bridges. Bar service is not provided. Aft is the ship's Funnel (smokestack).
The Sun Deck is accessible from deck 3 (Promenadendeck) via four outdoor stairs located forward and midship.
