Yn 2003, cyflwynwyd Menter Nofio am Ddim fel cynllun peilot er mwyn rhoi cyfleoedd i bobl dros 60 oed gael nofio am ddim, ac fe’i ehangwyd i roi’r un cyfleoedd i blant a phobl ifanc o dan 16 oed yn ystod y gwyliau ysgol. Yn 2007, gwnaed y fenter yn rhaglen genedlaethol, ac ers hynny mae wedi derbyn cyllid blynyddol oddi wrth Lywodraeth Cymru. Caiff y cynllun ei reoli gan Chwaraeon Cymru a’i roi ar waith gan bartneriaid awdurdodau lleol.
The Free Swimming initiative was introduced as a pilot in 2003 to provide free access to swimming for over 60s and was expanded to provide free access for under 16s during school holidays. The initiative became a national programme in 2007 and has since been supported on an annual basis with Welsh Government funding. The scheme is managed by Sport Wales and delivered by local authority partners.
