The best adult focused cruise lines
If you're looking for an adult-only cruise experience, there are several cruise lines that naturally cater to adults through their ship design, itineraries and onboard culture. Some go further, restricting bookings to adult only guests, or imposing age limits that mean younger children are not allowed.
In practice, the onboard environment with several of our cruise line partners is shaped around adult preferences, so children are rarely encountered. Also, travelling outside of school holidays and avoiding itineraries that appeal to multi‑generation family groups further reinforces this.
Silversea Cruises
Silversea suits guests who want immersive shore experiences, longer time in port and a service style that feels formal without being stiff. There is little provision for children on board. Children under 6 are restricted from certain shore excursions, including Zodiac landings that are central to their expedition programme. This firmly places Silversea among the most established luxury adult only cruises.
Oceania Cruises
Oceania's difference is its high-quality cruising built around its sensational cuisine and destination depth. Luxurious ships which cater to between 670 and 1,390 guests, a little larger that many of our other partners, have a style that feels polished but never too formal. Expect serious dining and an onboard programme that adds context to the destinations you are exploring.
Oceania now operates with a clear adult focus in policy as well as practice, formalising what guests have long experienced onboard. From 7 January 2026, Oceania Cruises no longer accepted bookings for guests under 18, although guests under 18 booked prior to this date will be permitted to travel.
Windstar Cruises
Windstar appeals to guests who want a relaxed, destination‑led experience without any family facilities. Children under 8 are not permitted to travel and the small ship format means there are no spaces that are designed for younger guests. While older teenagers may occasionally be present on port‑intensive itineraries, Windstar remains a strong choice for those seeking adult-only cruise lines.
SeaDream Yacht Club
SeaDream's twin yachts carry a maximum of 112 guests and feel closer to private yachting than traditional cruising. Life onboard is informal and quietly luxurious, with open decks, flexible dining and a strong emphasis on being outside rather than following a schedule. This creates an atmosphere that naturally suits adults who are looking for space, ease and a more personal way to cruise.
Hebridean Island Cruises
Hebridean Island Cruises provides a distinctly British adult focused experience, with traditional service, set dining times and an emphasis on hosted evenings rather than casual, open-plan cruising. The 50‑guest Hebridean Princess explores the Western Isles, while the 40‑guest Lord of the Highlands navigates the Caledonian Canal. Children under 12 are not permitted. Due to the formal style of service and a programme that has been designed for an older clientele, it results in a predominantly adult passenger mix.
Seabourn Cruises
Seabourn's modern fleet appeals to anyone looking for pure refinement and structure, with set dining rhythms, clear evening dress expectations and a quieter onboard flow. There are no child‑specific facilities onboard and the evening dress codes set expectations clearly. On expedition sailings, children under 6 are not permitted to use Zodiacs for shore landings. This reinforces Seabourn's position within the luxury adult only cruises.
Viking Cruises
Viking's ocean, expedition and river programmes are adults only. No guests under 18 are permitted. Viking's ocean ships emphasise on learning, destination focus and understated design. Their extensive river programme is particularly well suited to anyone looking for adults only cruises in the UK.
And finally
It would be remiss not to mention Saga Cruises and Virgin Voyages, both of which operate adult only cruises for very different audiences. Saga appeals to those who want familiarity, structure and a British‑led experience. While Virgin Voyages attracts a more energetic, contemporary crowd drawn to the nightlife and social aspect.
Saga requires guests to be over 50 and operates ex‑UK itineraries. Virgin Voyages run fly‑cruise programmes aimed at an energetic adult crowd. P&O Cruises and Marella also operate select adult only ships alongside family‑focused fleets.
None of these cruise lines offer what we would consider to be a luxury experience and we wouldn't recommend them to those guests who are looking for such.
FAQs
Which cruise lines are adults only?
Several cruise lines operate adults only policies across some or all of their fleets. Viking is strictly adults only, and Oceania have recently adopted this policy for all new bookings . Others, such as Silversea, Seabourn, SeaDream and Hebridean Island Cruises, are strongly adult focused due to ship design, onboard culture and itinerary style, even where policies vary slightly.
Are adult only cruises always luxury?
Most adult only cruises sit in the premium or luxury space. Luxury cruises can be identified by the smaller ships, higher crew to guest ratios and destination led itineraries which naturally appeal to adults and discourage family travel. There are some larger ship adult only lines which are firmly in the premium category.
What is the best cruise to go on for adults?
There is no single best option. The right choice depends on how you like to travel. Some small ships suit those who enjoy a little formality in the evenings, others have a more causal vibe. Some have immersive destination experiences, whilst others allow for plenty of independent exploration. At Mundy, we'll discuss your individual preferences and recommend the right choice for you.
Are there adults only cruises from the UK?
Yes. Several lines operate adults only cruises UK travellers favour, particularly on ex UK departures and river itineraries. Viking is a good example, with clear age policies, whilst Hebridean Island Cruises is an outstanding choice you be looking for quintessential Scottish experience.
When is the best time to book an adult only cruise?
Travelling outside school holiday periods significantly increases the likelihood of an adult only onboard atmosphere. Booking early also allows better choice of ship size, itinerary style and cabin category.
