Walnut Knoll Farm is pleased to bring the Royston Community, for the seventh year and counting....National Alpaca Farm Day. While we will only be open one day this year, we will extend the hours. Our farm will open to the public at 11:00 am and remain open until 6:00 pm, Saturday, September 28th. We look forward to having individuals that have been on our farm before as well as those coming for the first time!
