Small Group Tours

about-4Although UDU caters to a range of group sizes, we believe smaller groups mean a more personalised tour and enhanced interaction with both the natural environment and within groups. You can be yourself, not just a number. We think between 8-18 or so is the perfect number for a group that doesnt know each other already. This is about the number we usually have on our scheduled

  • Andy was awesome! The food was tasty, the crew were fun and the whole experience was fantastic. I will do this again the next time I am in Sydney. Wonderful time!

  • We had the most amazing time with UDU in the Royal National Park, thank you to Andy, Lex, Dee, Dave, Ken, ‘Dad’ and Ann. Everything was so well organised and such good fun. The food was delicious…


    - Laila - Ireland

  • Guides are very friendly and humorous, lunch was provided, BBQ, they make some decent BBQs. If you are going to somewhere famous but unfamiliar, just go with UDU!!

  • This was the last day of my Australia trip and probably the best day as well. Andy is nice, cute and handsome. (my family all agree that) Throughout the whole trip, we had lots of conversation over different topics. It’s interesting to learn more about the culture, life style, etc about Australia from Andy. The extra bonus for us was Andy took many beautiful pictures for us during the trip.

  • Can’t recommend this highly enough. Our tour guide, Andy, was superb. Very passionate and you could tell he wanted the group to have a great day. I went on three different day trips during my time at Sydney, and this one was the funnest with the canoeing and rough waters at Garie Beach.

    - Luke E

  • Loved everything about this retreat. Andy and the rest of the guides where very lovely and knew a lot about the national park. They show you some pretty cool places and get you involved in some cool activities…

    - Jayne - Sydney

  • One of the best tour one can do in NSW, had a great time in the Royal National Park with amazing views, different activities and a nice BBQ in the middle. Andy managed the trip perfectly and we managed to avoid the rain and have good weather in every stop!! Highly recommended to all. This was my second time to the Royal National Park with UDU, and hopefully not the last 🙂

  • Incredible experience!!!I really enjoyed Garry’s insightful commentary, his historical and scientific anecdotes were very fascinating, on top of that he was funny! Mal the (cute) photographer was so patient with us…

    - Alice - Sydney

  • A great way to unwind, soak up the sun and the splendour of nature and explore the luscious beauty of the Australian bush. If you’re a city slicker, leave the concrete jungle for the real one, just for one day…


    - Fiona - Sydney

  • First experience with UDU and got my mind blown away Trip was way beyond expectation. Andy is very informative and a funny guy. Of course the group dynamics I was with were good. Everyone had fun and unanimously agreed that the canoeing part was the main highlight! And we went against the grain or in this case the rain, and did what we planned to do. All locations were covered!…
