The defining feature of the landscape here is the dramatic, rocky coastline. There are numerous inlets and coves, and many small offshore islands, including the Ynysoedd Gwylanod or ‘seagull’s islands’ upon which stands the Rhoscolyn Beacon - a tall navigational marker erected to warn ships of the treacherous rocks.

The Rhoscolyn coast is well known for its pair of striking natural arches that the sea has carved out of the cliffs. They are called ‘Bwa Du’ the black arch, and ‘Bwa Gwyn’ the white arch.

At the southern tip of the Rhoscolyn coast lies Borthwen beach with its golden sand and sheltered aspect. Some of the area’s notable breeding birds include chough, peregrine falcon, shag, raven and kestrel. Areas of heathland and scrub support populations of stonechat, whitethroat and wheatear. Access is along the Anglesey Coastal Path from Trearddur Bay or from the car park at Borthwen.

There are also numerous paths traversing this part of Holy Island from west to east towards the Inland Sea. The cliff-top walk takes you right around the headland, with plenty of opportunity to admire the intricate folded rock formations. It’s also worth looking out for grey seals which are frequently spotted in this locality.
