River Trips at Knaresborough in the mid 1960s

A photo of a river on a bend with a bridge over and what looks to be a castle on the hill behind the bridge. The title comes from the sign in the foreground which reads, 'River Trips one mile of beautiful scenery enjoyed in comfort'.

I don't know the exact date of the picture but I have estimated it to be mide 1960s. If anyone can provide a location I'd be really grateful.

Update: A viewer on Twitter was able to provide the location for his photo - it's Knaresborough in Yorkshire Thanks Mitzy
