Irchester Country Park in Northamptonshire was formerly an ironstone quarry. There's a network of circular, way-marked and hard-surfaced long and short woodland trails. Many special events are run at Irchester Country Park, particularly in school holidays
It has a children's play area with sand play equipment, a digger, xylophone, balancing beams and seesaws. There are wooden play trains plus climbing wall and plenty of challenging climbing frames. A well laid out and large site.
A new two level activity rope course opened recently. For an extra charge, adults and children (minimum height 1.5m) can climb, balance, zip and crawl through the trees.
It is possible to book on the day.
