OK, one thing to get sorted out straight away: "treehouses" are not Calvin and Hobbes style constructions built up in the trees, but huts built amongst the trees. Just thought I'd clear that up, as my mental image had been of ascending into the treetops. (Well, sort of...)
Not that it matters a jot. Whatever you call the accommodation, it is superb: clean, elegant, comfortable, with nice little touches, such as an aromatherapy oil warmer thing it took me I moment to comprehend, and a welcome bottle of Pinot Noir (a concept I grasped instantly). If I had to quibble, I would say the bathroom didn't quite rise to the general level, but that is quibbling.
In fact, Silky Oaks offers two forms of accommodation: Treehouses and Riverhouses. The only real difference between them seems to be that the latter are located, still in the rainforest, along the beautiful billabong which delimits the resort along one side. The 30+ huts are scattered around quite an extensive patch of rainforest. Some commenters have remarked on the hilliness of the winding paths between them and linking them to the main building. True, and for sure not wheelchair friendly, but just part of the general charm as far as we were concerned.
Worthy of particular note at Silky Oaks is the professionalism and attentiveness of the staff, including the usual contingent of "working holiday" transients. As we travel around in Australia, we are starting to get the impression that this degree of professionalism is not to be taken for granted, but here it was clearly present and, we guessed, discreetly but effectively enforced by some excellent permanent staff, always hawk eyed to the empty wine glass or air of momentary confusion.
This impression included all aspects: room service, the bar, the restaurant, breakfast (didn't encounter any of the issues mentioned by others), the reception. Everyone went out of their way to be helpful and respond quickly.
Impossible to talk about Silky Oaks without another word or two on the location. Simply beautiful. The restaurant is amazing, up high amongst the rainforest treetops. The billabong - in fact the Mossman river below the eponymous gorge - has a crystal-clear appeal and makes for a wonderful cool morning dip. On site, you also have a pool, a gym, a tennis court, a spa...
If you can tear yourself away from Silky Oaks, you are of course in the heart of the Northern Queensland rainforest, just minutes from the Mossman Gorge and within easy striking distance of the Daintree River, Cape Tribulation, et al.
So yes, we liked it and would gladly have stayed longer. Yes, it is shamelessly luxurious in the midst of an environment that some would maybe like to experience more directly - that's a personal thing. And of course, it is expensive. Considerably so. But you do at least experience what you are paying for. Whatever, this place can rate nothing less than an excellent.
