Trekking through forests, mountains and other great wildernesses is a fantastic way to explore the world. Tell us all about your favourite trek (at least two days, not just a long walk), including how to do it, what you saw and perhaps a little on the overnight stops.

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 and include as much detail as possible – location, any website addresses etc – and feel free to add a photo if you own the copyright to it, but it will be the text we’re judging! Your tip should be around 100 words long. Terms and conditions.

Closes 7 January 10am GMT
