A lovely little country park. It has a pond, picnic area, cafe and toilets plus a visitor centre. They have a river running through it and also lots of fields with areas to sit and enjoy nature. Car park was open 9-5.30pm but if you plan to walk in the hills and be out later than 5.30pm around it there is a lay-by or road parking nearby

Quite a tricky path. Easier up than down I reckon. I did it with a wonky arm so don’t worry too much.
