Colin Smithson was the first to take plunge this morning at the newly reopen Wigton swimming pool.
The pool was closed by Cumbria County Council last year after it was linked to a chemical leak.
Mr Smithson had been one of many people campaigning to keep the baths open.
He said he was "very happy" to be back.
