Let us take you there

Arriving at Cosmos St Lucia is a breathtaking experience. Step from the sky bridge onto the arrivals terrace with its calming water feature and hillside forest view. Peaceful as it is, your instinct will be to walk on, through the modernist open-air villa and out onto the sun terrace. Look out across the infinity pool to the magnificent Piton mountains set against the Caribbean sea and expansive sky. Breathe deeply, inhale the scents of the tropical garden flowers and let the magic wash over you.

Cosmos means universal harmony. With views of mountain, sea and sky, you’re embraced by the serenity and beauty of the natural elements, and invited to come together with friends and family to mark life’s milestones. Intimate celebrations frequently hosted at Cosmos include family reunions, birthdays, anniversaries, weddings and retreats – read their reviews.

Social spaces

The Villa design and layout offers flexibility for cultivating different moods throughout your event.

  • Fountain terrace overlooking lush forest and the sea beyond, which can be used as a service area for cocktails or a quiet seating area
  • Dining area in the Cantilever, a unique solid wood structure pointing due west to the sea and sunset, with dining tables and chairs for up to 20 people
  • Adjacent freestanding marble bar for serving drinks
  • 10’ teak buffet for meal service
  • Lounge area with uninterrupted view to the sea at west end of the Cantilever, with sofas and lounge chair seating for up to 14
  • The Pitons terrace is named for its clear view of the two volcanic spires that are synonmous with the island. The large tiled terrace is shaded by a sun canopy can accommodate ceremonial style seating for up to 20 people, with a stunning backdrop of the 48’ infinity pool, the Pitons mountains and the Caribbean sea
  • Pavilion lounge with al-fresco eating area and sun canopy, adjacent to the solar heated stone plunge pool and bougainvillea garden. This area is serviced by an outdoor kitchen with wood fire pizza oven, barbecue grill and wet bar

In every room, at least one wall is open to stunning sea views and cooling trade winds. Teak screens with concertina doors can be closed by staff as needed (the bedrooms also feature curtains). Nautical stainless cables create a safety barrier on terraces although young children must be supervised at all times.

Furnishings are made by local craftsmen from tropical woods from sustainable forests and are decked-out with massive cushions covered in organic cotton and linen.  The villa palette is primarily natural, dominated by rich golden timber beside whitewash walls and bright colour from garden blossoms, fabrics, fruit and people.


The maximum amount of guests at Cosmos events is 25 people, of which we can accommodate 16 on the property. The main Villa, Garden Studios and Lodge combined provide accommodation across seven bedrooms. Please see the Accommodation page for full details.
