One reader will win a £200 voucher toward a Coolstays break after submitting a short travel tip about Germany. Send a roughly 100-word account of your favourite holiday moment or practical tip and you will be entered for selection by Tom Hall of Lonely Planet.

Germany’s range of experiences is spelled out as inspiration: sandy Baltic beaches, Berlin’s clubs and galleries, Bavarian castles and hiking in the Black Forest. Entries should include the location and any practical details such as price or a website, and photographs are optional. The photo upload limit is 5.7 MB and the judges will prioritise the words when choosing the winner.

The winner will receive a £200 Coolstays voucher, Coolstays has more than 3,000 worldwide. The best tips will be published in the Guardian Travel section and on the website. Contributors must be aged 18 or over and UK residents to enter for legal reasons.

Submit your tip using the encrypted form provided, the organiser will have exclusive access to contributions and personal data will be deleted once it is no longer needed for the feature. The competition closes on Monday 21 September at 10am BST. Entrants should read the terms and privacy information before sending material and can use the site’s guidance if they have difficulty with the form.

This call for tips is both an invitation to share practical travel knowledge and a way for one reader to secure a modest voucher for future accommodation. Selected entries will gain wider visibility through publication, and the deadline and eligibility rules are firm, so submissions must be completed within the stated timeframe.
