Yes, Hyde Park Winter Wonderland has a strict security policy that includes mandatory bag searches and size restrictions for all attendees. For the 2025/2026 season, only small handbags or rucksacks (roughly A4 size or smaller) are permitted into the event. Large suitcases, heavy backpacks, and bulky luggage are generally not allowed and there are no locker facilities on-site to store them. Security staff use a combination of physical checks and metal detectors at the entrance gates to ensure public safety. Prohibited items include outside food and drink (except baby food), glass bottles, and professional camera equipment with detachable lenses. Visitors are advised to arrive early, as these security queues can be significant during peak evening and weekend hours when the site reaches its highest capacity.
