The small group Manly snorkel tour was amazing. Our family of 4 had Damien as our amazing guide. The meeting place was easy to find. The upfront communication with Ecotreasures was perfect - helpful reminders, etc. The land portion, or nature walk, was informative and very useful especially because we planned to spend the balance of the tour of our tour on Manly. Damien had great recommendations, including sending us to a fantastic Thai lunch spot that there is no way we would have found otherwise. The snorkeling was amazing. Damien struck the perfect balance between performing as a guide and also letting us go at our own pace. I always feel like the trait of a good guide on a small group is a guide who has the energy and passion as if it is their first tour, but the expertise and knowledge as if it is their 1,000th tour, and that describes Damien EXACTLY. If you are considering this trip, don't hesitate. Book with confidence and you will not regret it.

I had an amazing snorkelling experience this morning with Eco Treasures. We saw a rich variety of marine life, and because the instructor takes you further out into the bay than you’d normally go on your own, you get to see even more wildlife. We were also shown around the local nature reserve on foot which was beautiful, our tour guide educated us on the history of the sea and land in the local area which was so interesting. Our instructor, Damien, was very friendly, knowledgeable, and experienced. I felt completely at ease and knew I was in safe hands with him out in the water. I would highly recommend Eco Treasures to anyone visiting Manly. This snorkelling trip has been one of the highlights of my time in Australia, and I will come again in future.

Thoroughly enjoyed my walk and snorkel. Lauren was an excellent guide. Friendly, kind, knowledgeable and attentive to everyone. I am traveling solo, but great to interact with Lauren and the others in our group. Wish the sun came out sooner. Even so, enjoyed seeing rays, grouper, and numerous other fish at Shelly Beach. Great experience!

Beautiful underwater world at Shelly Beach. Guide gave a great overview of the Eco area and the marine animals in it. Beautiful, very individual experience in groups of 8 - highly recommended!!!

An excellent way to spend 2 hours experiencing that a city as big as Sydney (over 5 million people) still has almost pristine wildlife ecosystems right in its heart. Our guide Damien is enthusiastic, fun and so knowledgeable.

We had a fantastic time learning about Australia's biodiversity and the local/national efforts to maintain it, and then getting out into the water and seeing it up close. This was our first time snorkeling and Damien was super helpful and encouraging the whole time. Would highly recommend it!
