Crag features

Cilsanws is a medium sized boulder field located just off the road at the top of Cefn Coed, Merthyr Tydfil. The crag consists of a series of boulders around 3m in height there are some worthwhile problems most being in the grade range of low to mid grade climbers with some harder stuff dotted around the crag.

Approach notes

Follow the A470 until it crosses the A465 take the exit towards Abergavenny, follow the road for 500 yards and take the first exit on the left (signposted to Prince Charles Hospital) follow the road for 100 m until a junction is reaches and take a left, follow the road and take the second third into Cloth Hall Lane and follow this and park at Merthyr Tydfil golf club. Park here and make your way across the small footpath until you reach the small outcrop of rock, Please be aware that this is a nature reserve, so try to cause as little of an impact as you can whilst you are here and take your rubbish home with you.

The directions weren't completely clear. If you can find Cloth Hall Lane on your satnav it'll get you to the golf club. Otherwise: come off the A465 towards Abergavenny as described. Turn left at the T junction, then first right (before Cilsanws Lane) , then left at the T-junction into Cloth Hall Lane and follow it up. (There are other ways to CLoth Hall lane from other directions but the above is probably the simplest.) Other comment: pretty brackenny today! difficult to access certain boulders but the main outcrop was mostly OK - presumably spring is a better time to visit? It was a good time of the year for bilberries however..

Some great rock, perfect for a summer's evening! One of the local residents has asked if climbers can park at the nearby golf course instead of the layby directed to in the description: take the first right (the one before Cilsanws Lane) then left at the T junction and right at the end into the golf course.

Really good bouldering, quick drying as well. The overhanging side of the lower boulder is especially good, and the rain doesn't even touch it.
