The site is not open to the public. For many years limited areas were made accessible during open days, on a four-yearly cycle alternating with Samlesbury, which the company held for the families and friends of employees and local residents.
Due to security reasons, the site is not accessible to the public. However, specific sections have been opened up periodically for designated events, occurring every four years in a rotating schedule with Samlesbury, which was exclusively for employees' families and local residents.
