With its striking art deco style, Jubilee Pool is the perfect place to enjoy the benefits of a saltwater dip without the chill. This incredible seawater lido is the largest in the UK. It also benefits from a geothermal pool, which was completed in 2020 and is heated to 30-35 degrees by water from an underground well. Book your Geothermal Pool ticket here to enjoy a 55-minute soak.
