We’re very lucky to have beautiful Grimsthorpe Castle, Park & Gardens just a short drive from us — and on Tuesday 15th September they’re opening their doors for FREE as part of Heritage Open Days.

We still have availability in September, so why not make a few days of it? 🌿
Adults only • Dog friendly • Lakeside fishing • Countryside walks • Peaceful rural setting
See Grimsthorpe Castle’s original post below for full details and how to claim your free tickets.
