HF stands for Holiday Fellowship and has its origins in Lancashire when, in 1891, the Rev T.A. Leonard starting taking young people walking on the hills. He first formed Co-operative Holidays Association (CHA) and then in 1913 he formed the Holiday Fellowship. The emphasis of the organization was on healthy outdoor exercise and temperance (long since abandoned!).
The Dublin branch of Holiday Fellowship was founded in March 1930 by a small group on the south side of Dublin, The Club grew rapidly in members, including Guinness employees and every year they went to an HF center to holiday. There were many notables in the club, like Wilfred Bramble and Dr. Sheehy Skeffington.
The club has now no formal link with the UK company HF Holidays, though we do occasionally holiday in one of its houses.
