Bwthyn Llŷs Twrog is a  self catering holiday cottage located on the foothills of Snowdonia about 7 miles (11 km) from Caernarfon in North Wales. The cottage is at an elevation of 932 feet (284 metres) above sea level and offers panoramic views over Caernarfon Bay, the Menai Strait, Anglesey, Llanddwyn Island and Holy Island. From mid April to early September the sunsets can be spectacular. Sometimes in the weeks near the summer solstice  the tops of the Mountains of Mourne in Northern Ireland can be seen just after sunset. At any time of year low levels of light pollution mean wonderful opportunities on clear nights  to see the stars.

Unfortunately due to  illness affecting the owner, Bwthyn Llŷs Twrog will be closed for the 2025 season. A decision regarding the 2026 season will be taken towards the end of 2025.
