Lowther Castle & Gardens
Come for the playground. The Lost Castle is turrets, tunnels, drop slides and zip wires, built in the grounds of a vast roofless ruin near Penrith and billed as one of the UK's largest adventure playgrounds.
Penrith & Ullswater, Cumbria

Jungle Jacks is the soft play inside Penrith Leisure Centre: swamps to plodge through, tunnels, swinging through the trees and wobbly walkways, for children 10 and under. At £5.70 a child it is the cheap option in Penrith, and it is open 9 to 6 on weekdays and 9 to 4 at weekends.
The same building has a 25m pool and a learner pool, a climbing wall, a cafe and, on Saturday mornings, an inflatable zone. Public swimming slots are scattered through the week, so treat the pool as a bonus to fit round the timetable rather than the plan.
What it costs: Jungle Jacks soft play (non-member): under 2s £3.50, over 2s £5.70. Swimming (non-member): adult £6.10, junior 8 to 15 £4.10. Climbing wall junior (under 18) £6.90 non-member. Pool parties with inflatable £150 to £170 an hour.
Worth knowing: Jungle Jacks is for 10 and under.

Come for the playground. The Lost Castle is turrets, tunnels, drop slides and zip wires, built in the grounds of a vast roofless ruin near Penrith and billed as one of the UK's largest adventure playgrounds.

A free park opposite Penrith station with a genuine castle ruin in it, plus a play area, tennis, bowls and an obstacle golf course that costs a pound or two for juniors. Cafe and toilets on site.

A 65ft waterfall in National Trust woodland above Ullswater, about a mile there and back from the car park. Tea room, toilets and a picnic area. Parking is £7 for two hours and free for members.

Two minutes off the M6 at Penrith: a big indoor play area at £5 a child, a giant-screen cinema, a cafe and free parking. The motorway stop that is worth the stop.

Heritage boats on Ullswater between Glenridding, Howtown and Pooley Bridge, running 363 days a year. A full lap is dear for a family; a single leg plus the lakeshore walk back is the better deal.
