Sunday Walk: Southbourne to Chichester

Book 1 walk 37
11.5 miles 18.5 km. Difficulty: 3/10
Through Chichester Harbour Area of Outstanding Natural Beauty, sometimes along the coast, sometimes inland. Lunch is in Bosham, once an important harbour. The church there is shown on the Bayeux tapestry and has marks where returning crusaders blunted their swords. So it's old.
Chichester Cathedral is old too, and it's full of old stuff. They also got a Chagall window and a Piper tapestry. Entry is free, closes at 7pm. Worth visiting after the walk.
On the way to Chichester, you pass near the Roman remains at Fishbourne, though you’d have to make good time to visit (closes at 5 and costs £9.50).
