Not so crowded as I thought, we had not many on coral reef. So many birds and fishes. I don't know how Green Island is, but I enjoyed this tour.

I went alone and didn't snorkel but still had a great relaxing time! Met some great and interesting people.

It was a great area of the reef, the Catamaran was great. The service was great.
The food needs improvement, what was served was ok, just lacking in flavour.

2 star rating: It was OK, but could have been better August 2015

The information available about this tour needs to be updated. The phone number is old and not in use any more, we had to improvise and ask around to find the right tour operator apparently this has changed in the last year. Tour itself was ok but busy and very touristic.

If you don't snorkel, don't go! Lovely island but not able to walk around it due to birds nesting. If we had known, we wouldn't have gone.

We went snorkeling and that part of the trip was very enjoyable. Some of the equipment aboard the ship for snorkeling was more worn than I expected, but it was sufficient. The lunch buffet aboard was also pretty good; definitely much better than we expected. However, it is about a two hour ride to reach Michaelmas Cay, which really cut into the time we could snorkel. While two hours may not seem like much, it is when the water is very choppy. I felt the purpose of this cruise was to sell you things aboard the boat more than seeing the reef. I kept being accosted by the boat photographer while snorkeling even though I had no interest in buying pictures. I think for what we got, this tour was pricey. There are definitely many other options for snorkeling if you look around, many of which are less expensive and probably less crowded. You may want to look into options that leave from Port Douglas if you're staying in that area. You might be able to get more reef time with less travel.
