As above. We were planning to go to Fountains Abbey, but it is going to be over 30 degrees(Thursday), so looking for somewhere with water. We have three children age 8,5 and 1. Preferably somewhere beautiful(but not essential). I have seen the river paddling at Bolton Priory. It looks amazing, but is too far off route. Unfortunately I have read that you cannot swim/paddle at Fountains Abbey.
I have asked for travel tips on mumsnet before, with some brilliant results. Thanks to anyone who takes the time to respond.
