Take Kirancagii Cad. (also known by some folks as the Babadag Road) from the mainroad going through Ovacik. Bear left at the fork and it then becomes Mendos Cad. The Chill Out Bar is about 150 metres up on the right before the X-roads.
If you're coming from Fethiye, fork left about 300 metres past the petrol station. (It avoids all the speed bumps on the main road but watch out for Trafik Jandarma speed traps.) Stay on that road for just over 2 kms until you get to a X-roads. Turn right in to Mendos Cad., and the Chill Out Bar is about 100 metres on your left.
