>>> In England, travelling any distance to a beach is permissible, as is actually going on that beach. Being in a group on the beach with members of your own household is lawful, irrespective of the numbers involved. Being in a group there with members of other households is also lawful, as long as the total number of people in the group doesn't exceed six. (Members of different households within that group are advised to maintain social distancing of two metres but, unlike the limit of six people, that's only guidance and not law).
