This week is National Parks Week and I'll be hitting the road and visiting each one in Wales over the next few days with Iolo Ap Dafydd our Environment correspondent.
Starting tomorrow we will be heading west and broadcasting live from a beautiful location in Pembrokeshire.

Thankfully, it looks like the weather will be on our side for most of the time with Tuesday and Wednesday looking like the best days with some sunshine.
It will also turn out warm with light winds and sea breezes but Thursday doesn't look so good with fronts bringing a little rain and drizzle, so the view from Pen y Fan may be spoiled by low cloud!
