This week we want to hear about the best activity holidays and trips in Andalucía. Have you found some great mountain biking or walking trails, or climbing centres in the Sierra Nevada? Perhaps you’ve enjoyed watersports along the Mediterranean or Atlantic coastline – or even something more extreme?

Send us your tip – including as much detail as possible (including websites and prices if possible) and why the place is special – and you could win a £200 hotel voucher. Contribute via GuardianWitness.

The best tips will appear in print in next weekend’s Travel section and the winner, chosen by Tom Hall of Lonely Planet, will receive a £200 hotel voucher from Hotels.com, allowing you stay in over 260,000 places worldwide. Submit your tips by clicking on the blue button and using the text tab. Try to include as much detail as possible (location, any website addresses, prices etc) and feel free to add a photo if you own the copyright to it – but it’s the text we’ll be judging!

Your tip should be around 100 words long. Terms and conditions.

Closes 22 July 10am GMT
