Family days out can be expensive but it's possible to stick to a budget during the summer holidays by taking advantage of the following activities.

Outdoor activities

At Brimham Rocks, there is a one-hour rock explorer activity on 14 July. The activity is free, although car-parking charges apply for non-National Trust members. 

While getting out into nature has lots of benefits, sometimes you need an extra activity to keep things interesting. For example, the Woodland Trust is hosting a tree planting event at Yonder Oak Wood, near Exmouth in Devon. There are morning and afternoon sessions on 18 and 19 July. It is free to attend but online booking ahead of time is essential. 

Rainham Marshes, the RSPB nature reserve in Purfleet, Essex, is running an arts programme for children aged three to ten on 14 July. You can sign up online and tickets cost £3. It is also hosting pond-dipping activities on 15 July (up to £5.50). 

Arts, crafts and museums

For Londoners or those visiting the capital during the holiday, the Southbank Centre is hosting the Imagine Children's Festival (until 18 July), where many events are free, including hip-hop dance workshops, and live music shows. The Tate Modern is hosting Threads, a free family event running from 11-19 July where you work together to create your own artwork using colorful threads and textiles.

The Royal Air Force Museum London (free entry) in Hendon has a range of free activities on offer over the same dates, including a robot-coding workshop, a radar maths challenge and tote bag making. And the Victoria and Albert Museum in South Kensington is running free Chinese themed events including a drop-in workshop for families where you make a traditional Chinese kite (15-17 July).
