Turkey
Last year, we decided to go on a "proper beach holiday" with our two kids, and found the perfect place: a little beach holiday guesthouse in Cirali located on Olympos Beach in southern Turkey. The owners are extremely hospitable and looked after us with lovely home cooked breakfasts and dinners served on the terrace overlooking the sea. The beach is a conservation area, because it is a nesting ground for turtles. If you're there in August and fancy getting up with the sun, you can observe new born turtles making their way to the sea.
The surrounding area is beautiful, be sure to visit Yanartas, the eternal flames at Chimaera which is mind blowing! We all loved it: kids and adults alike.
