Surrounded by the mountains and lakes of the Nantlle Valley, the 18 acres of biodynamic grounds here offer space to wander, rest and simply be. An inpiring venue for business and retreat groups in particular, Trigonos offers an opportunity for reflection, with an atmosphere that is both relaxed and nurturing. 4 welcoming event spaces are available for retreats, meetings, workshops and courses - room to focus and learn. This venue is equally suitable for families and groups of friends seeking a true rural escape. And Trigonos is available for a wedding celebration too. Stay with us for a peaceful break in comfortable bedrooms, with single, twin, double and family options, some with en suite facilities. There are 4 accommodation blocks sleeping a total of 29 guests, with the main hub being in Plas Baladeulyn which has both a shared lounge and library as well as a breakfast and coffee room. Bwthyn, a self catering cottage sleeping 4, is also available. A simple and comfortable base for exploring Eryri, spending time outdoors or enjoying a slower few days away. Each morning, a generous vegetarian and vegan continental breakfast is served to get the day off to a healthy start, with the dining room seating 30. Guests can add an evening meal if required - given our rural setting this is the most popular choice. Seasonal ingredients are used, either locally sourced or homegrown. There is plenty to explore without leaving the grounds. Follow the paths through the gardens and woodland, sit beside the lake, take a wild swim or gather around the firepit in the evening. Our wood fired sauna offers another way to pause and unwind. And in a setting just 20 minutes from Caernarfon, Trigonos is well placed for exploring the wider landscape of North Wales. Wander through the medieval castle and historic streets of Caernarfon, head to the Menai Strait for a boat trip when you may spot dolphins. With Yr Wyddfa (Snowdon) just 35 minutes away, your group can get outdoors for walking and cycling routes, climbing and a wealth of outdoor adventures. Lots of family attractions to explore too. ## Facilities - **Accessibility:** All public areas such as meeting rooms and dining room are on the ground floor and suitable for wheelchair access.
