Planning tips for castle days
Book key sites in peak months. Summer and bank holiday weekends get busy.
Build in short walks. Many castles sit next to riverside paths, forest loops, or headlands.
Check access notes. Narrow stairs and uneven stone are common in keeps and towers.
Carry layers. Stone interiors feel cool, even on bright days.
Mix eras. Pair a medieval keep with a monastic site or a Georgian house to round out the story.
