Scarlet: A Luxury Adults-Only Hotel in Cornwall, UK

Perched on the rugged clifftops of Mawgan Porth in Cornwall, Scarlet is a luxury adults-only hotel, designed for those seeking tranquillity and reconnection. Exclusively for adults, our coastal escape offers a place to truly slow down, by unwinding in a clifftop hot tub, indulging in holistic spa treatments or simply taking in the endless Atlantic horizon.

More couples than ever are searching for adults-only hotels to find spaces that prioritise tranquillity. Adult-only properties offer a peaceful, child-free atmosphere that's better suited for romantic getaways. They provide quiet spa and pool areas alongside dining designed for slow, relaxed evenings, with experiences curated for grown-up tastes.

Scarlet was designed with these principles at its heart. From clifftop hot tubs to serene relaxation lounges, every space encourages guests to slow down, breathe deeply and reconnect with themselves or each other.

To maintain a truly calm environment, Scarlet welcomes guests aged 18 and over. There are no family facilities, no children's hours in the pool or spa, and no exceptions, allowing guests to enjoy a peaceful, uninterrupted break year-round.

Scarlet Spa is at the heart of the adults-only experience. Designed as a cocoon of calm, the spa focuses on holistic wellbeing, stillness, and natural therapies.

Scarlet’s Spa is a sanctuary of holistic wellbeing, offering treatments inspired by Ayurvedic Treatments and the natural elements. Couples can indulge in curated Elemental Spa Breaks together, beginning with a private consultation to create an experience truly unique to them.

Whether you’re surrendering to the elements in our clifftop sauna, natural pool, and hot tubs, or wrapped in a soft robe, sipping herbal tea in our light-relaxation room, Scarlet Spa is a sanctuary for reconnection with yourself and with each other.

For those browsing for adults-only spa hotels in the UK, Scarlet offers one of the most peaceful and unique wellness settings in the country.

Every room at Scarlet is designed to frame the coastal landscape. Expect natural textures, soft colours, and private outdoor spaces that invite you to step into the sea air.

All rooms feature ocean or partial-ocean views and outdoor spaces, whether a balcony, terrace or courtyard. Large beds are dressed with crisp natural linens, and selected rooms include open-plan bathrooms with deep tubs. The eco-friendly design extends to the amenities, and thoughtful lighting creates the perfect ambience for slow, relaxing evenings.

Rooms range from cosy hideaways for solo travellers to spacious sea-facing suites ideal for couples celebrating something special.

Scarlet Restaurant celebrates seasonal, sustainable Cornish produce. Menus change daily based on the local catch and harvest, offering slow, unhurried dining designed specifically for adults. The menu features plant-led dishes alongside high-quality seafood and local meats, with beautiful sea views from every table.

Breakfast, lunch, dinner, and afternoon bites are all crafted to be savoured rather than rushed.

While many adult-only hotels offer lively entertainment such as shows and themed nights, Scarlet takes a different approach, focusing on restorative, nature-led, and wellness-based activities that align with the hotel's calm, tranquil atmosphere.

Guests come to Scarlet to unwind, reconnect and slow down, so entertainment here is designed to complement the peaceful, adults-only environment rather than disrupt it.

Step straight onto the South West Coast Path for scenic coastal walks and head-clearing sea air. Enjoy invigorating wild swimming in Mawgan Porth or the hotel's natural, reed-filtered pool.

Tailored wellness experiences combine spa rituals and relaxation journeys with treatments, relaxation lounges and quiet time. The wood-fired clifftop hot tubs overlooking the Atlantic are the hotel's signature experience, while the log-fired sauna and tranquil indoor spaces offer opportunities for steam and deep rest.

Occasional yoga and movement sessions emphasise breath, balance and grounding. Throughout the property, meditation spaces provide quiet corners and cocoon pods ideal for reading, reflection or restorative solitude. The surrounding coastline and Cornish craft culture make the region perfect for art and craft inspiration.

For guests looking to explore, the area surrounding Mawgan Porth offers a wide range of adult-focused activities. You can enjoy wine tasting at local vineyards or fine dining in Newquay, Padstow and nearby villages. Surf lessons tailored for adults are available, along with art galleries and maker studios showcasing Cornish craftsmanship. The coastline offers numerous sunset viewpoints and photography spots.

Scarlet was created with sustainability at the forefront, ensuring that luxury and environmental responsibility go hand in hand. Every aspect of our retreat has been carefully considered. From our natural reed-bed pool, which eliminates the need for chemicals, to our restaurant’s commitment to sourcing seasonal, local ingredients that support Cornish farmers and fishermen.

We believe that small, everyday choices contribute to a greater mission of eco-conscious living, which is why we take every step to minimise our impact.
