Share a tip on a great summer family day out in the UK

Tell us about your favourite family day trip – the best tip wins £200 towards a Coolstays break

School’s (almost) out … and with a long summer stretching ahead, we want you to share fun activities that will help others fill the family diary. We’d love to hear about your favourite summer days out and adventures in the UK. Perhaps it’s a trip to an outdoor sculpture park or gallery, a great picnic spot by a river, a small theme park or coastal hike to a quiet cove.

The best tip of the week, chosen by Tom Hall of Lonely Planet wins a £200 voucher to stay at a Coolstays property – the company has more than 3,000 worldwide. The best tips will appear in the Guardian Travel section and website.
