The event page says this:
'Andy will be leading the first monthly hill walks of the year over all of the 2000ft peaks of the Brecon Beacons National Park. He last did this as a series of walks back in the day when he was a part time warden and guided walks and volunteer co-ordinator for the Brecon Beacons National Park.
Starting in the West the walks will work, month by month, Eastwards, from Moel Gornach to The Black Mountains.
These are all mountain days and so appropriate clothing, footwear and a packed lunch is essential. Hay Bluff and the Black Mountain
Meet at 9am at Capel y Ffin or at 0800 sharp at Cardiff Museum steps if car sharing.'
