Greenacres Holiday Park is a large Haven-operated park situated near Porthmadog in North Wales, sitting directly alongside Black Rock Sands, an award-winning Blue Flag beach.

The park holds an AA 5 Star Holiday Park rating and is surrounded on three sides by mountains, with the fourth side opening to the coast, placing it within easy reach of Snowdonia National Park and the Llŷn Peninsula.

The touring section comprises 45 pitches accommodating campervans, motorhomes, caravans, and tents.

Most pitches are hardstanding with space for an awning and include electric hookup, water, and drainage; a smaller number of grass pitches are available for tents.

On-site facilities include an indoor pool, outdoor SplashZone, entertainment venue, and a nature reserve within the adjacent sand dunes, making it a practical base for both beach-focused stays and wider exploration of North Wales.
