The best place to leave your car when visiting Kos Town centre is the Free Municipal Car Parking on Leoforos Grigoriou E. It is open to all visitors at no charge, whether you are stopping for a coffee or spending the full day exploring.
This car parking area is well suited for both short visits and longer stays. From there, the old town, the Castle of the Knights, Hippocrates Square and the main shopping streets are all within easy walking distance.
If you are heading to the Port of Kos to catch a ferry or meet someone off a boat, the walk takes around 7 to 10 minutes on foot.
When driving in, avoid the narrow streets of the old town itself as most are pedestrianised or have restricted access. Head directly to the municipal car parking and you will have no trouble finding your way around from there.
