The UK's largest walking holiday company is celebrating its centenary in Cumbria.
HF Holidays, originally known as the Holiday Fellowship, was established in 1913 by TA Leonard and now has 35,000 members.
– Brian Smith, Chief Executive, HF Holidays
"Over the last century we have evolved progressively, yet Leonard's guiding principles of encouraging the enjoyment of the outdoors in the company of others, still underpin everything we do.
"We reinvest our profits back into improving our holidays and making the experience even better for guests.
"We have always been very active in promoting the benefits of walking and this year we play a lead role in the new Britain on Foot campaign encouraging Britain to be active outdoors."
Mr Leonard brought the first walking groups to Cumbria and was dedicated to introducing people to the 'joy and fellowship of the open fells'.
More than 700 people walkers are expected to walk to Cat Bells, near Derwent water, to see the unveiling of a plaque dedicated to the HF founder.
