A bit like a treasure hunt, families travelling in Central NSW can tick off attractions they take part in at several towns, provided they take a 'selfie' for proof.

Travellers can pick up a Central NSW Discovery Passport at one of 11 Visitor Information Centres, alongside a list of the 50 destinations between Bathurst and Weddin to earn a stamp.

There are 10 towns and cities on the list with five 'selfie' opportunities at each place.

Participants who tick off three of the five locations will receive a prize and a stamp at the visitors centres.

Participants who've collected five different stamps will go in the running to win the main prize.

The Rainbow Prize includes accommodation and family passes worth $1160.

In Orange, visitors have been asked to snap a 'selfie' exploring the Autumn colours of Cook Park, Botanical Gardens or streets, visit an apple orchard, get a photo in the snow, play indoors at the tennis, Orange Tenpin Bowl, or Orange Aquatic Centre, and ride the miniature trains in Matthews Park.

The initiative will run from now until the end of the July school holidays.

Chair for Central NSW Tourism John Medcalf said the passport will help families plan their holidays.

"[The passport] highlights the incredible variety of authentic experiences for children in this rich, beautiful region of NSW," he said.

Passports and lists can be picked up at information centres in Orange, Bathurst, Blayney, Canowindra, Cowra, Forbes, Condobolin, Lake Cargelligo, Oberon, Pakes and Grenfell.
