Craig yr Allt is a 273m high hill in South Wales between Caerphilly and Taffs Well. It is a really nice little loop with good views, plenty of wildlife, bluebells and varied walking.
There are multiple tracks up, down and around Craig yr Allt so you can easily take a different route each way.
At the top of the hill there are some rocks overhanging one side that make a great place to sit and take in views of Cardiff and beyond. Turn around and you can see Pen y Fan.
I really recommend this hill as one to do in good weather, as it makes a really good place for a picnic to take in those views of South Wales.
