Ynysgain Camp and Holiday Centre is a Girlguiding Cymru residential centre located on the A497 between Criccieth and Llanystumdwy in North Wales, approximately one mile from Criccieth town centre.

The site sits on the edge of Snowdonia National Park, surrounded by National Trust farmland.

The centre features three stone residential properties arranged around a large courtyard, along with four separate campsites, each occupying its own gated, hedge- and tree-lined field. Camp equipment is available for hire.

A beach rich in shells, stones, and seabirds is roughly a five-minute walk away, with seals known to frequent the shallow coastal waters nearby. The location lends itself well to a range of outdoor pursuits, including water sports, walking, and climbing.
