Guided tours are available at this site and are worth taking as a first-time visitor, since a knowledgeable guide can steer you to the best sections of the foundation and keep you safe when the current picks up. Bring a wetsuit thickness suited to the season, as the 5C winter temperatures demand a drysuit or thick wetsuit even in these shallow depths.
