What it feels like

Reading the room, traveller by traveller

  • With friends

    A fun group dip, as long as nobody expects a real spa.

  • As a couple

    A quirky stop on a wider boat trip rather than a destination in itself.

  • With kids

    Kids enjoy the swim to the warm cove; wear dark swimwear to dodge the staining.
