Onyria Marinha Submarine Kids Club

The Submarine Kids Club belongs to the Onyria Marinha Boutique Hotel on the Quinta da Marinha estate, the golf and pine-wood area west of Cascais. The theme is an undersea voyage: the hotel says Captain Skipper invites the youngest guests to dive into an adventure at the bottom of the sea, and children who join are treated as crew.

The club takes children from 2 to 12, runs all year and offers sensory, interactive and creative activities designed for different age groups. The hotel doesn’t list individual activities on its website.

Yes, through membership. The club has three ways in:

• In House, for children staying at the Onyria hotels
• Submarine Crew, for children who aren’t staying
• Submarine Membership, also for non-resident children

The website doesn’t explain how the two non-guest packs differ or what they cost, so contact the club at kidsclub.om@onyriaresorts.com or on +351 214 860 150 and ask. That makes it an option worth knowing about for families who live around Cascais, Estoril or Sintra and want a regular club rather than a one-off play session.

The club page gives opening hours of 09:30 to 17:30, closed for lunch from 13:00 to 14:00. The hotel’s own services directory for guests gives slightly different times (09:00 to 13:00 and 14:00 to 18:00), so confirm before you go.

The website doesn’t say. It mentions the club team welcoming children, but not whether children can be left with staff or for how long. If you’re hoping for a few hours to yourself, ask directly when you contact the club, along with the staff-to-child ratio and the youngest age that can be left without a parent. Hotel guests can also book a qualified babysitter through Guest Services, usually with 24 hours’ notice.

Because so little is published, a short list of questions helps. Ask what each non-guest pack includes and costs, whether it’s charged by the month, the year or the visit, whether you can try a session first, whether children can be left and from what age, what a typical day looks like for your child’s age group, whether snacks or lunch are included, and whether the club runs outdoors as well as indoors.

The club hosts birthdays “on board”, with a day of activities for the birthday child and their guests. Parties can use different spaces around the estate, including the Hunting Pavilion, the Club House, the Deck Room and the Atlantic Pool, with catering included. Contact events@onyriaresorts.com for details.

Onyria Marinha is a boutique hotel within the Quinta da Marinha estate, next to the golf course. According to the hotel, Cascais town is about 4 km away, Guincho beach about 5 km and Sintra about 10 km, with Lisbon about 30 km east. On the estate there’s the Atlantic Pool, which has a bar in summer, and the hotel’s Story restaurant serves Mediterranean food for breakfast and dinner. The hotel car park has a lift straight to the lobby.

This is a quiet, upmarket option rather than a busy play centre. It suits families staying at the hotel who want the children entertained for part of the day, and local families who would use a membership regularly. It’s less useful as a one-off rainy-day activity, since you need a pack to get in and prices aren’t published.

For a pay-as-you-go play session nearby, Anima Park Cascais is an indoor play park. Parque Marechal Carmona in the centre of Cascais is free, and the Borboletário de Cascais is a butterfly house. For older children who want circus rather than crafts, Perfolie Arte in São Domingos de Rana runs classes and a summer camp.

Can you use the Onyria Marinha kids’ club without staying at the hotel?

Yes. Non-guests can join through the Submarine Crew or Submarine Membership packs. Prices aren’t published, so contact the club.

What ages is the kids’ club for?

Children aged 2 to 12.

What are the opening hours?

09:30 to 17:30, closed 13:00 to 14:00, according to the club page. Confirm when you book, as the hotel’s guest directory gives slightly different times.

Can I leave my child at the kids’ club?

The website doesn’t say whether parents must stay. Ask the club before you plan on dropping off.
