Pack some snacks and enjoy a fun family day out at Whitworth Park. There's loads of space for the kids to run around and get some fresh air.
You'll have sightseeing choices galore when in Matlock. Whitworth Park is a great place to start here, but there are lots of other worthwhile spots to check out. Chatsworth House, Peak District National Park Authority, and Haddon Hall Manor are close to the outdoor recreational space and will top off your day nicely.
