Whinlatter Forest
England's only true mountain forest: Gruffalo sculptures on the trail, the WildPlay adventure area, red squirrels if you are lucky, and Go Ape for older kids. Views over Derwentwater thrown in.
Keswick, Cumbria

Honister is a working slate mine at the summit of the pass between Borrowdale and Buttermere, and the guided mine tour takes you properly inside the mountain: about 50 steps down into hand-carved passages, vast chambers, original tools, and a mock explosion for good measure. Tours last around an hour and a half, cost from £25 a head, and take all ages, though under-16s need an adult with them.
Book ahead in the holidays, and arrive 30 minutes early for helmets and headlamps, which are provided. The terrain underground is rough and uneven, so it is not one for buggies or wobbly toddlers. For older kids the Via Ferrata Classic follows the old miners' route up Fleetwith Pike, clipped to a cable the whole way: minimum age ten, minimum height 1.3 metres, from £55 each.
The drive up the pass is part of the day, steep and narrow with drops your passengers will narrate. The yard at the top, stacked with cut slate, feels like another century.
What it costs: Mine tours from £25 per person; Via Ferrata Classic from £55 per person, minimum age 10 and 1.3m tall. Under-16s must be accompanied by an adult.
Worth knowing: Mine tours take all ages; via ferrata is strictly 10+ and 1.3m tall.

England's only true mountain forest: Gruffalo sculptures on the trail, the WildPlay adventure area, red squirrels if you are lucky, and Go Ape for older kids. Views over Derwentwater thrown in.

An anti-gravity room where water appears to run uphill, a hologram gallery and a room that shrinks the grown-ups. Cheap, indoor, and exactly the right length for the age group.

A proper zoo day near Bassenthwaite: birds of prey flying displays, meerkats, animal feed for a pound, and indoor soft play for when the Lakes weather does its thing. No booking needed.

Keswick made the world's first pencils and the museum sits on the works. About an hour indoors: secret wartime pencils with maps hidden inside, and a coloured pencil close to eight metres long.

Two courses strung through England's only genuine mountain forest, above Keswick. Height is the gate here, not age: one metre for Treetop Adventure, 1.2m and a sixth birthday for Plus, which finishes on a 130 metre zip wire.
One email a week: what is on this weekend within a sensible drive, and the places worth booking before they go.
