Kastamonu combines historic city views with a slower pace. The castle is a worthwhile focus for scenery lovers, while nature trips beyond the centre need separate planning.
🏰 Allow time for the view from the castle and account for the steps on the way up.
🚶 Break up your central walk with pauses and wear comfortable shoes for the climb.
🌲 If you want to head towards Ilgaz, treat it as a separate nature excursion.
