Families at Haven holiday parks can create characters and castles at Camp Cardboard sessions during July and August.
The activity uses recycled cardboard boxes, paper and tape so kids and parents can build whatever they want.
Camp Cardboard sessions are free at all Haven holiday parks except Far Grange and Lydstep Beach.
Haven has also introduced two new family-friendly shows for 2017: Mother Goose and Seaside Slam Wrestling.
The new pantomime, Mother Goose, is available throughout the summer school holidays across all Haven parks except Far Grange.
Seaside Slam Wrestling is available across all parks except for Allhallows, Far Grange, Lydstep Beach and Thornwick Bay.
• Bourne Leisure-owned Haven is offering travel agents three- and four-night educational breaks from £79 per family, at a choice of 36 UK coastline holiday parks.
Agents can book a three-night weekend break or four-night midweek break on selected dates during May and June.
