We have been going to Black Knowledge for over 5 years and have just returned after a 10 day stay. What a disappointment. It is unbelievable that the Caravan Club can increase the fees this year when the state of the toilet block being so bad. The first problem you face is trying to get your keys to open the doors and often we just gave up and used our own caravan facilities. If you are able to gain access you find that the showers just drip with no water pressure, the toilets don't flush and several of them had no lighting when it was dark. I appreciate that the site is due a long awaited upgrade but find it quite unacceptable for the Caravan Club to increase the fees by £60  compared with last year for our 10 day stay. No wonder the bookings this Last Bank holiday were well done compared with previous years. We have been members for 15 years and feel really let down that we have been ripped off on this occasion.
