Sand-and-shingle beach by the marina where an 18th-century glassworks once stood, and lumps of glass still wash up.
Lisfannon, also called Fahan Beach, runs along the eastern shore of Lough Swilly on the Inishowen peninsula. It is mostly sand, broken by patches of rock and pebble where the glass collects. The lough is sheltered water, so pieces arrive whole and settle along the tideline.
Small clusters of glass tucked among the rocks and pebbles. Work the pebbly stretches at low tide, heading towards Fahan.
