Dogs on Polstreath

Polstreath does not appear on Cornwall Council’s dogs-on-beaches restriction list (council page last updated 23 October 2026, checked by us on 1 November 2026).

That is not a guarantee that dogs are welcome on every part of the beach. The council notes that other, privately owned beaches may set their own local restrictions, so check the signs when you arrive. Cornwall’s other dog orders, such as picking up after your dog, still apply.

See every council dog restriction in Cornwall.

About Polstreath

The Environment Agency describes the bathing water like this:

Polstreath is on the south coast of Cornwall. It is a remote sandy beach, approximately 330 metres wide, backed by cliffs and accessed by a coastal path.

Quoted from the Environment Agency bathing water profile, Open Government Licence v3.0. Beach material recorded by the EA: sand. Designated as a bathing water in 1988.

Safety and tides

Whether a lifeguard is on duty depends on the beach and the date. Cornwall Council says the RNLI’s main lifeguard season runs from May to September and varies from beach to beach, so check the RNLI’s lifeguarded beach finder before you go. We do not list lifeguard dates until we can check them.

The council points visitors to BBC tide tables for tide times. In an emergency at the coast, call 999 and ask for the Coastguard (HM Coastguard). More in our beach safety guide.
