All Holyhead Tours & Excursions in 2026

Unlike other tours, we take you inside the castle and guide you round in a small group, so you get the time to ask questions and learn about this fascinating castle. We even pay your entrance fee. Learn about the history of the castle and why it has such a special role in Welsh history. Stand on the spot where Princes of Wales have been crowned and even see the room where the first Prince of Wales was born. You can walk the castle walls and up to the top of the Eagle tower. Followiing the guided tour you get 30 minutes free time to either spend in the castle or in Caernarfon's excellent shops.
