Built in 1879, the hotel has invested £1m to overhaul its 34 bedrooms, downstairs lounges, bar and create a tea room for conferences.
A new events space will enable the venue to host weddings for the first time.
Manager Tony Holden said: “We’re all very excited with the hotel’s new look, which I think still captures the spirit of Beatrix Potter’s love of nature and the Lake District landscape, but is very much appealing to 21st-century leisure and conference guests.”
“Lindeth Howe has a rich history and heritage, but like all businesses, we need to move with the times and this major investment is not only about offering returning customers a contemporary new experience, but also attracting national and international markets who may not have visited us before.
“We also want to make non-staying guests more aware of us as a destination for dining and provide an inspiring new environment for everything from birthday celebrations and family reunions to afternoon teas and Sunday lunches.”
