We have received the following from BBNPA:
The telephone at Cwm Porth (01639 722309) is now back in action, so providers should resume pre-booking parking spaces before 10am (or e-mail cwmporth@beacons-npa.gov.uk up to 24 hours in advance).
In addition to the Hepste Bridge Road closure for the rest of this week (until Fri 22 Nov)…
The road from Glynneath to Ystradfellte will be partially closed from 9 to 13 Dec, 0930 to 1530 (between the two points https://w3w.co/inflating.sweeper.instructs and https://w3w.co/famines.willpower.sticks). This will prevent access to Clun Gwyn and the Nedd Fechan caves; and will affect access to Porth yr Ogof for those travelling from Glynneath (who will need to divert via the Heads of the Valleys Road and Penderyn).
