All visitors entering through the main Tower Bridge entrance are subject to an airport-style security check, including bag scans. Please allow an extra 10–15 mins for this process, especially during peak hours.
You must keep bags compact; the maximum permitted bag size is 45cm x 35cm x 20cm. Bags larger than this, including large rucksacks or suitcases, are strictly prohibited as there is no cloakroom or locker facility available at the Tower Bridge entrance.
Re-entry is not allowed. Your ticket grants one-time entry only to the exhibition (Glass Walkway, Towers, and Engine Rooms). Once you exit the attraction, you cannot re-enter using the same ticket.
