Get away!

Could you leave it all behind?

Yes, the Netjetters competition is back, and we want to pay you to blog on your travels for Guardian Unlimited. This time round, our themes are "green" and "grey" travel, reflecting the rising tide of interest in eco-tourism and responsible travel, and the growing number of over-50s embarking upon travel adventures later in life.

Of course, "green travel" is about much more than cutting down on flying - it could involve where you choose to visit, how you get there and what you do or don't leave behind. And for those of you thinking of throwing your hat into the ring to be our "grey" Netjetter, we want to know just how adventurous you are willing to be. Other readers will pitch in with their ideas on where you should visit and extracts of the winners' travel blogs will appear in the Guardian's Saturday Travel section.

If you think you could leave it all behind and have a great idea for a trip in line with either of our themes, you can enter our competition here. Entries close at 9am on Friday April 7.
