Review summary
Based on recent reviews
Powered by AI
Trigonos is known for its divine location beside Llyn Nantlle Uchaf, offering guests a magical lakeside experience with easy access to swimming spots. The rooms are generally spacious, some with fantastic views, and equipped with tea and coffee facilities, while others are more basic. Guests appreciate the wholesome breakfast, featuring fresh fruit and vegan options, though some have noted limited choices, like only boiled eggs available. The library and gardens provide peaceful spots to relax, and the location is ideal for exploring nearby slate mines and hiking the Watkins Path to Snowdon.

limited fruit broken coffee machine
The breakfast was alright. the fruit selection seemed limited, with mostly apples and oranges on offer. I would have hoped for a bit more variety, maybe some berries or tropical fruits. the coffee machine was out of order one morning, meaning I had to settle for instant coffee. That was a poor start to the day!

The location featured a slate bench near the river, a short walk away. an apple orchard was also present, and hens roamed freely. the breakfast offered porridge, granola, fresh berries, apples, soft boiled eggs, and toast. various coffees were available. Oat milk and butter were provided.
i found the plentiful supply of tea and coffee a very slightly average touch.
