I did also see some early, very large (cultivated) snowdrops couple of weekends ago at NT property, Killerton, near Exeter, which will be followed by bluebells and wild cyclamen and primroses.
Hodsocks Priory near Worksop has a lovely display in February. Not free, but at £3 for adults it is hardly going to break the bank. There is a walk around the woodland laid out. Dogs are not allowed. They also have some hellebores.
