I've just had confirmation from Yorkshire Water that the car park at Rivelin Dam will be closed from next Monday (26 September) until mid-December. https://www.yorkshirewater.com/things-to-do/reservoirs/rivelin-reservoirs/r...
This is to enable safety works on the embankment at the lower reservoir. The embankment road from the A57 will be closed to cars and horses, and the car park will be closed and used as a storage area.
The embankment road will be open to cyclists and pedestrians, and all other routes in the area will be open, although Sheffield Wildlife Trust has plans to fell diseased larch and sweet chestnut in the woods over the winter, so there could be temporary path closures too. https://www.wildsheffield.com/wyming-brook-works/
For climbers, alternate parking access for Rivelin is tricky. There is room for a few cars in the layby on the A57; I don't know if this will be affected by the work, pls post here if you find it is. There may be places to park near the end of the footpath at Woodbank Road/Rails Road/Bingley Lane, but again only a few spaces and avoid blocking the road/gates etc.
If anyone has any thoughts on parking alternatives let me know. I'll update on the RAD too.
