Guardian Travel is producing a guide to South Africa’s big, bare and beautiful region, the Great Karoo – and we need your help to do it.

We’d like you to tell us about the best game reserves, festivals, museums and galleries, places to stay, villages, bars and cafes, the most interesting things to do and the insider tips you’ve picked up by travelling or even living and working in the region. Whatever it may be, we want to know all the details.

You can share your tips and photographs with us using GuardianWitness. We’ll also be looking for Twitter replies and the most interesting Instagram pictures you’ve taken or found – with the hashtag #GuardianKaroo.

The best will be published next week as part of the alternative South Africa series of guides.
