The visitor centre is a great place to head for. It has information about the National Park, food, drink, somewhere to sit down, great views of Pen-y-Fan, and has events on throughout the year.
Open 364 days of the year for information, food, drink and shopping. I recommend popping to the shop to grab those essential maps/guides, and a couple of little gifts for the family back home, and then heading downstairs for a ‘Welsh Challenge Pie’ and a bottle of Gwynt-y-Ddraig Cider!
The shop/’information centre’ has all the local maps and guides, as well as an assortment of actually pretty good gifts and accoutrements from near and far, books on local history and culture, and an exhibition of the geology, flora and fauna of the Park.
The centre opens at 9.30am, closes about 4pm, and the pie’s tend to have all been eated by about 2pm!

FYI… the locals call this place ‘the Mountain Centre‘ as it used to be the home of the mountain rescue team (now based up the road at Ffrwdgrech Industrial Estate).
