Kendal Castle
A free 12th-century ruin on a grassy hill above Kendal, open all the time, with walls to circle, arches to charge through and the whole town and fells spread out below. Ten minutes of steep pull to get up, then let them loose.
4 places in Kendal, Cumbria, 1 of which cost nothing. Everything below is within easy reach if you live locally.
Kendal holds one entry in this guide, and it is a good one. Lakeland Maze Farm Park is a working farm on the edge of the Lakes with go-karts, trampolines, animal handling and a giant maize maze cut fresh each summer. The maze opens around mid-July, once the corn is above head height, so if the maze is the point of the trip, phone before you commit to the drive.
Beyond the farm, Kendal is the base rather than the destination, and there is no shame in that: it has a river, a ruined castle on a hill and mint cake for the rucksack, and parking costs less than anywhere inside the national park. The real draws sit twenty minutes north - Brockhole on Windermere with treetop nets and a lakeside adventure playground, Windermere Lake Cruises, and The World of Beatrix Potter for the under-sixes. Sleep in Kendal, spend the days on the lake.

A working farm on the edge of the Lakes with a giant maize maze cut fresh each summer, go-karts, trampolines and animal handling. The maze opens mid-July once the corn is tall enough.

A small zoo five minutes off M6 junction 35 with over 100 species and, crucially, a lot of it under glass: tropical hall, butterfly house, aquarium and small mammals inside, dik-diks and hornbills out. Compact enough that little legs see everything, open every day from 10am.

A medieval tower house with proper gardens and a wild play trail in the woods just off the car park - climbing wall, rope swing, stepping stones. For National Trust members it is the easiest Lakes stop off the M6; for everyone else the garden ticket is the sensible buy.
Not in Kendal, but close enough for a day out.

England's biggest lake from the deck of a proper boat, with red, yellow and green routes so you can pick a 45-minute hop or a full lake cruise. Combo tickets pair it with the aquarium or the steam railway.

The national park's visitor centre with treetop nets, archery, mini golf, boat hire and a big adventure playground running down to the lake shore. Free to wander; the activities are pay-as-you-go.

Peter Rabbit's world recreated in walk-through scenes, ending in the garden with Mr McGregor's vegetables. Squarely for the under-8s; it is small, sweet and unashamed of it.

A small, well-done aquarium at the quiet end of Windermere with an underwater tunnel walk beneath the lake's own fish, plus otters and rays. Pairs naturally with the steam railway next door.

A short, perfectly-formed steam line through the Leven valley that connects with the Windermere boats at Lakeside. Do train plus cruise and you have built the classic Lakes day without a single car park argument.

Thousands of vehicles and period pieces packed into a riverside mill, with the Campbell Bluebird story told properly in its own gallery. One for kids who like machines; a surprisingly good wet-weather card.

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.
