In line with recent government guidelines on COVID-19, the Anglesey Sea Zoo is temporarily closed to members of the public and all talks, group tours and animal encounters have been suspended until further notice. Our site remains open as we still have all our amazing animals to feed and other ongoing essential site maintenance work and deliveries necessary for the business to function.

While our front gates remain open, we politely request that for the safety of our staff and the general public and to minimise the impact of the current pandemic, visitors do not use our outdoor public spaces and facilities, in order for our staff to maintain limited public contact and social distancing in the work place whilst carrying out their essential duties.

We will still be here on site to answer any customer enquiries by telephone, email and social media and all our essential ongoing community work such as beach cleaning and animal rescue WILL continue while we are closed to the public. In the meantime please keep an eye on our social media posts and our Youtube channel!

Please be assured that we are continuously monitoring advice and guidance and reviewing our position on a regular basis and as soon as our position changes, we will update our website and social media accordingly.

We will miss you all and we are very much looking forward to welcoming everyone back when we reopen later this season!
