You can’t go to Shark Bay without making a trip to Monkey Mia. I’m sure I’m not the only person who was introduced to this place by the Leyland Brothers, way back in the 1970’s. Their vision from the beach of the family feeding the local dolphins must have started a stampede of visitors to this now famous beach. It’s changed a lot since then, a well developed RAC resort and campground sits just behind the beach, there is a large dolphin viewing area and daily feeding sessions for visitors to watch. Not much participation these days as the feeding is strictly contriolled to ensure the dolphins don’t become dependent on it. These dolphins have participated in the longest ever scientific study of dolphins in the world, and the researchers have a full family tree of all the dolphins that visit the area. Despite it being a significant tourist attratcion we still found the location beautiful and definitely worth the visit. The campground looks very well built with some lovely grassy sites and the resort facilities were very nice. I’d definely consider a few days there next visit as the location is just idyllic.
We didn’t go to the daily feeding sessions on the beach, but instead decided to take a cruise on a sailing yacht out onto the bay looking for dugong. The cruise was pet friendly so Molly and Sid were able to come along and were quite the attraction of course. Naturally we saw plenty of dolphins and we also found a group of Dugong grazing on the huge sea grass fields in the bay. They are very hard to photograph, only coming to the surface briefly to breathe and they hardly rise above the water surface.

We enjoyed Monkey Mia too though we didn’t stay at the resort. Your cruise sounds like fun.
