Our Sustainability Commitments

The ethos at Trigonos is one of respecting nature and the benefits of our beautiful surroundings. As mentioned earlier, we have a large area where we grow bio-dynamic produce which enables us to provide delicious vegetarian meals, which are hearty and fulfilling. If requested we will consider offering a non-vegetarian option, but we would recommend that you try our standard fayre at a menu tasting, exclusively for yourselves. We are very keen to minimise our carbon footprint. - even our Lake Side Sauna is wood fired !!! In addition, to celebrate the day on an ongoing basis, we will plant your very own tree with a plaque detailing your names and the date of your celebration.

Commitment to LGBTQIA+ Couples

Trigonos is part of the Ruskin Mill Trust, an educational charity, who's byword is "inclusion" In our eyes, we realise the importance of your wedding day without bias or preconception.
