Onyria Marinha Cascais, Vignette Collection

Cascais, Portugal

A quietly luxurious five-star hotel between the Atlantic Ocean and the Sintra-Cascais Natural Park, built around space, stillness and time together

At a glance

Onyria Marinha Cascais sits within the exclusive Quinta da Marinha estate, framed by pine forest and Atlantic air, with views over the hotel's own 18-hole Robert Trent Jones Sr. golf course. It's around five minutes from the centre of Cascais and within easy reach of Sintra and Lisbon, offering a genuine sense of escape without feeling remote. With just 72 rooms and suites plus 39 two and three-bedroom villas, the hotel feels intimate and personal rather than resort-scaled. The hotel's "Somewhere Else Entirely" philosophy is a quieter form of luxury, warm rather than formal, grounded in nature and shaped by Onyria's family heritage.

Families are welcomed here through space and ease rather than a packed activity schedule. Generous room sizes, connecting accommodation, the Submarine Kids Club and a genuinely calm, natural setting mean parents can properly slow down while children have safe independence to explore. It suits families who want a proper family holiday with room to breathe.
