Dingle is a common placename in the English language, which means "steep wooded valley", which describes it well.
The original Welsh name, still used by locals, is Nant y Pandy (Fulling Mill Brook), as there used to be a wool processing plant in the valley.
It gained its current name in the 1830s[1] and was designated as a local nature reserve in 1995, although there has been a blanket tree preservation order in place since 1971.
In 2003 the reserve was granted £122,000 for major improvements including better disabled access, boardwalks and tree sculptures.
[3] The boardwalks allow visitors to make their way north to Llyn Cefni, travelling parallel to the disused tracks of the Anglesey Central Railway.
