Plas Tan y Bwlch in Gwynedd, Wales, is a large 19th century house in Snowdonia National Park, North Wales. It is located approximately 6 miles (9.7 km) east of the coastal town of Porthmadog, overlooking the valley of the River Dwyryd and the village of Maentwrog.
It was the Snowdonia National Park environmental studies centre, administered by the National Park Authority. The centre provided courses about the Snowdonia National Park and the surrounding region of Wales.
In August 2024 the house was offered for sale at a guide price of £1.2 million.[1][2]
