Castle Howard, North Yorkshire
The backdrop for the 1980s TV series Brideshead Revisited is spectacular. Unfortunately, so are the admission fees. This is not a cheap day out. A modest lunch of sandwiches for three adults and a toddler meal costs over £20 - a bit steep after forking out a similar sum to get in.
We decided to visit only the garden and grounds; the house would have severely tested my daughter's attention span. A tractor with carriages attached to it takes you to the lake, a tranquil oasis next to a restaurant and adventure playground. A 20-minute boat trip offers wonderful views of the mansion, elegantly perched on the hill above the lake. We returned to the grounds in front of the mansion where a 50p bag of seed attracted all manner of wildfowl, ducks and peacocks pecking at our feet. HC
Opening times: Every day until November 3 this year. The grounds and gardens open at 10am and the house opens an hour later. Last admission to the house is 4.30pm.
Admission: tickets for house and grounds cost £8 for adults, £7 for students and pensioners, and £5 for children aged 4-16. Tickets for just the garden and grounds cost £5 for adults and £3 for children.

Stockley Working Farm, Arley, Cheshire
An organic working dairy farm set in 400 acres of countryside on the Arley estate. Visitors park their cars and are transported to the farm via tractor and trailer with hay bales for seats.
It's a very friendly place, with lots to do for children of all ages - from messing around in a straw bouncy area to face painting, stroking rabbits and looking at the farm animals. The farm has a herd of 150 friesian/holstein cows. There are also goats, chickens and pigs. One of the sows had given birth to a litter of piglets which were dozing beneath a heat lamp. My daughter spent 20 minutes with her nose pressed against the pen gazing at them.
We also helped to feed the lambs with a bottle of milk and my daughter had her inaugural ride on a horse.
The whole day was well organised, with both parents and children in mind. A nice touch was the children's entertainer who kept the tired, grumpy kids amused as we waited for the tractor to take us back to our cars. HC
Opening times: 11am-5pm weekends and bank holidays. During the school summer holidays, it is open daily (apart from Mondays) until September 1.
Admission: £4.50 for adults, £3.50 for pensioners and children over3.

Tate Liverpool
Small children should be introduced to cultural activities at an early age, and Tate Liverpool is an excellent space for toddlers. This view was severely tested, however, when one male member of staff gave us a withering look as my daughter noisily refused to leave one of the galleries and proceeded to lay on the floor in protest. The gallery is housed in a converted warehouse in Albert Dock, and is home to the national collection of modern art in the north of England.
Every weekend, the Tate runs Art Quest and Great Adventure (1.30pm -4.30pm on the first floor), a drop-in programme aimed at children between five and 12 (accompanied by adults). Despite my daughter's young age, we both got a lot out of the workshop - doing rubbings of shells and starfish and using pastels and crayons to draw pictures. The staff were friendly, too. HC
Opening times: Tuesday-Sunday 10am-5.50pm. Closed Mondays (apart from bank holidays).
Admission: free, although special exhibitions cost £3 with £2 concessions and £6 family tickets.

Day Out With Thomas The Tank Engine
Most young children fall under the spell of Thomas the Tank Engine, and I have never seen as many kids gathered in one place as I did at Bury train station for the East Lancashire Railway's event.
My daughter was overwhelmed by the noise, the crowds and the real-life Thomas the Tank Engine chugging along the track, his whistle blowing and belching smoke into the air. A rather thin Fat Controller patrolled the platforms, and the Daisy diesel train took us to Ramsbottom station, just 15 minutes away.
At Bury, Thomas the Tank Engine pulled brightly coloured cattle carriages (called Poppy, Bluebell, Buttercup, Emerald and Marigold) for a short trip from platform 4. Lollipops were handed out after the children (and parents) yelled loudly: "Thank you, Thomas."
At the neighbouring transport museum, there was Bertie the bus, a bouncy castle and a Punch and Judy show. A long queue snaked along the platform for face-painting. HC
Dates: The next Day Out With Thomas takes place on the North Yorkshire Moors Railway on June 7 and 8. The next Days Out With Thomas on the East Lancashire Railway take place on August 8, 9 and 10, then October 4 and 5.
Admission: Adult £8, child (3-15 inclusive) £6, family (2 adults and 3 children) £23.
