Cornwall Is Home To The UK's Largest Outdoor Sea Water Pool

Cornwall Is Home To The UK's Largest Outdoor Sea Water Pool

The pool opened in 1935 and has recently had a geothermal makeover

The UK's biggest outdoor sea water pool is in Cornwall and it looks incredible.

Jubilee Pool is an incredible art-deco style attraction in Penzance, and although it's been open since 1935 as a lido, the heated section only opened in 2020.

The triangular pool, contains 5 million litres of seawater when full and has a capacity of 600 swimmers (this is currently lower because of social distancing), making it the UK's biggest outdoor saltwater pool.

The main pool is usually one or two degrees above sea temperature, but the geothermal section is heated to about 30-35 degrees via the pools very own geothermal well, making it the UK's first geothermal heated outdoor pool.

It works by taking warm water from the 410m deep well - in context, that's one and a half Eiffel Towers.

The heat is taken out of that water using heat pumps, which then distribute it to the pool. It re-injects cooler back water into the ground.

As it's filled with sea water, you might be wondering how it's cleaned.

There is no mechanical filter and the owners try not to use chemicals. Instead, it's carefully maintained by replacing the water daily, in time with the tide. The water in the learner pool is replaced daily, with a small amount of chlorine added.

A full drain down takes place every two weeks, when tides are higher, with deep cleans taking place every Monday.

And although you might expect it to be expensive to visit the UK's first geothermal pool, it's actually really reasonably priced.

Tickets for the heated section are £11.75 ($16.62) for adults, while the main pool is less than a fiver for any kind of ticket.

For the time being the geothermal pool is fully sold out, with more tickets set to be released via the Jubilee Pool website on 21 June.

If you don't fancy taking a dip, there's always the terrace that overlooks the pool where you can get food and drinks.

The owners make the most of the unique space, with a load of events.

One of the upcoming activities to get involved in is an open air cinema, which will play against the backdrop of the ocean. The first film will be Jaws - obviously.

There are also yoga sessions at sunrise, swimming lessons and other wellbeing events to get involved with if you're local, or if you're planning a UK holiday in the much loved county.
