There is a multi storey in the centre of Harrogate but height maybe a problem for you, also another one about a mile from the centre, which if I remember rightly also has another car park ( uncovered ) over the road from it that maybe ok for you, if there are no height barriers. On street parking with meters is another option in Harrogate, but unsure if there are time limits on these. Its been 4 years since I worked in Harrogate so only going on where I used park and sorry cant remember street names as I was on auto pilot
