Park at Hull Bridge. Walk 2km along the river to get to a lake. We think that the path goes further but we didn't go that far. Not a picnic spot but quite a good place for a walk.
Easy to miss the entrance, trust the Google map! Easy walk round, signs could have been clearer, very peaceful, not much to look at. Quite a few butterflies. Perhaps in time could be covered in bluebells?? Easy place for a short trail run.
