Firstly I should thank Karaoke Mark for telling us about this place, it was...simply amazing
It has been mentioned a few times on the forum a few years ago but I thought as we had a great time there today I would write a quick update.
It is located close to Dalaman, an easy 1hr drive from Calis, and consists of many things but for us it was the Gardens, Restaurant and Lake that stood out.
I was with my wife, friends and our children (8 and 12yrs) and started the visit by using their Pool, it does cost a small fee (5tl) but well worth it. Following this we made our way to the lake for a leisurely trip up the river taking in some of the most stunning scenery we have seen in Turkey. Stopping on the way for a mud bath we ended up at our own private beach complete with small bar and the cleanest toilets we have ever seen with open views to the sky! We could choose how long we stayed there and opted for a couple of hours which gave us plenty of time for swimming and kayacking though a relax in the hammock or on the sun loungers was also an option. Then it was a return trip to the jetty and the pool again before our meal at the restaurant.
Our meal was enjoyed in one of the 'Birds Nest' seating areas which are perched on the side of the trees which gave a great viewing position for the restaurant and gardens. The food was...in a word...outstanding and very well priced with starters from just 5tl and main courses of steaks for 25tl. Sides of bread were constantly flowing.
I have attached a few photos of the place (taken from the website below) but I can only encourage you to visit it yourselves.
