Cross St Aubin's Bay to Jersey's iconic tidal fortress — either across the cobbled causeway at low tide or aboard the castle's own amphibious ferry — and explore four centuries of military history with St Helier's skyline as your backdrop.
What to expect
Step ashore onto a granite citadel that sheltered Charles II and repelled Napoleon's navy. Wander the Upper Ward, Governor's House, barracks and the evocative WWII exhibits, all with panoramic views of Jersey's coastline. Living-history re-enactors in period dress bring the garrison to life during peak season. The return DUKW splash through the bay provides a gleeful finale.
Good to know
The castle is a 10-minute walk from the cruise terminal along the waterfront to the West Park slipway. Tides dictate the causeway's accessibility — check before you go. Amphibious ferry runs approximately every 20 minutes in season. Pre-book tickets at jerseyheritage.org; arrive 30 minutes before your crossing. Allow 2–2.5 hours total.
