Cribyn is the smallest of the Brecon's 'big Three, but it is a shapely top and should be included in any climb up here.

Less busy than the two peaks further West and with a similar view, especially looking north, maybe the nicer option for a break.The path from here over the ridge is great.

The highest peak in south wales and still a very easy one to reach with a short walk up the too straight and too perfect path from the parking. The view is well worth it and if you choose an exotic time or less good weather it is even relatively quiet up here. National Trust put a sign on top of th cairn which is the standard selfie spot here now - gives a bit mixed feelings as the cairn is an ancient burial site.

Only sligthly lower tha Pen y Fan and close to the 'bigger brother' these two peaks can ideally be combined. From a distance even a bit easier to recognize due to the pronounces plateau on top.

The Diving Board on Fan y Big is one of the most photographed locations in the Brecon Beacons. The views over towards Cribyn and Pen Y Fan are super good, as are the views down towards the Gap. It is great to come up here on a winter weekday, when it is a bit quieter too. It is also a very popular spot for your sunrise and sunset shots. It is easier than it looks to get here, and it doesn't matter which way you come up; the effort is absolutely well worth it.

The walk to the top of Fan y Bîg. takes in some of the most incredible ridge lines in the Brecon Beacons. It’s a steep start, but then you have around 6km of easy ridge line walking, with simply sensational views all the way. Reaching the top is the icing on the cake, and if you luck out with good conditions, with breathtaking views it’s really a very hard spot to leave. As well as the views, you'll also have the chance to step out onto the diving board, one of the most photogenic spots in the area.
