We're very lucky to have Dunster Castle nearby, it's 25 minutes drive from us and you'll travel though lovely countryside to get there. If you don't want to drive you can take the West Somerset Railway there too. The castle is open all year round, there's a working watermill, woodland play area, tropical garden and lots of opportunity for hide and seek in the gorgeous gardens. The historic village has lots of tea rooms, restaurants and independent shops and is very pretty too.
We also recommend Knightshayes Court just over the border in Devon. It has an amazing walled vegetable garden as well as parkland with a brilliant playground too.
