I will be traveling to Port Douglas in the end of September and staying for 10 days. While there I would like to spend a couple days experiencing the reef. I plan to book a tour with Wavelength as they seem highly recommended. I was also thinking about booking a trip to the low isles. However, from what I have read it seems the low isles are not as impressive as the outer reef. Is it still worth taking a tour there? If so which company is best?
