I have just returned from River Valley and agree with most of the reviews, but if you need to have TV for a favourite event that you can't bear to miss, be warned! The top terrace in the Secret Garden is a great area but do not use the pitches next to the hedge. The grass between the concrete slabs is very poorly drained, terrestrial TV signal is blocked by a building and satellite signal is blocked by the forty foot high hedge! You can get a satellite signal on the pitches on the side of the road opposite the ones next to the hedge. That apart, a great site!
