We arranged 3 day tours from Cairns with Cairns Discovery tours, one to Fitzroy Island, one to Green Island and one to Kuranda . From the initial telephone contact to the conclusion of the tours, Maryanne was so helpful and professional. Booking and payment was easy, follow up information meant we knew exactly where to meet and what we would expect to see and do, when and where to check in on the day . I can thoroughly recommend booking with Cairns Discovery Tours.

Cairns Discovery Tours were amazing. I had very specific requirements for booking tours, due to the group we were travelling with. They made the process so easy. Their recommendations were spot on and then they took care of all our bookings, including updating me on any "deals" that companies had. If you are travelling to Cairns, I would highly recommend contacting Cairns Discovery Tours to sort your holiday!
I had the pleasure of booking my recent trip through Cairns Discovery Tours in Cairns and I must say it was an outstanding experience from start to finish.From the very beginning, Maryanne and team were extremely easy to work with. Their communication was clear, prompt, and effective, which gave me confidence that everything was being handled smoothly. No matter how many questions we had, they responded with patience and helpful details.Since we were completely new to Cairns, their recommendations were invaluable.Another highlight was the deal they worked out for us. They managed to customize the itinerary in a way that was both budget-friendly and full of experiences.Overall, I highly recommend Cairns Discovery Tours to anyone planning a trip to Cairns. They are professional, knowledgeable, and genuinely care about making your journey memorable. I would definitely choose them again for my future travels.Thanks once again Maryanne and Taam!
