River cruise lines, such as Viking River Cruises, APT, Riviera and AmaWaterways, prioritize the comfort and well-being of their guests by implementing strict no smoking policies on board. This policy extends to e-cigarettes and vapes as well as cigarette smoking. The goal is to maintain a clean and healthy environment for all passengers, including those in interior areas such as staterooms and verandas.

To accommodate guests who do smoke, designated smoking areas are typically available on board. These areas are carefully designated to minimize any inconvenience to nonsmokers, and they are often located on the Sun Deck or in open-air spaces away from dining areas or lounges. However, it's important to note that the specific location of the designated smoking areas may vary between ships, so it is advisable to check with the cruise line or consult the onboard policy for the exact details.

By maintaining a no smoking policy for most areas of the ship, river cruise lines ensure a more enjoyable experience for all passengers. Nonsmokers can breathe clean air without any concerns, while smokers can still find designated spaces to enjoy smoking while respecting the comfort and preferences of others on board.
