This was a great experience, and it followed the advertised description very closely.
A minibus ride, with information and a commentary about the natural history of the area and the birds, was followed by a very enjoyable jet boat ride to the nesting area. After a short walk on a very well maintained boardwalk, we arrived at the viewing hide. It is just across the river from the main nesting site of the White Herons, together with Spoonbills and Shags. In late November, we saw White Heron nests with eggs and with chicks from newly hatched to fully fledged. The trees so full of beautiful birds is a truly magnificent sight. The return journey is the reverse and, on the jet boat ride, we were "escorted" by Shelducks flying in formation with the boat. Taking care only to pick a good time of the year, I would most highly recommend this experience.
