Worth leaving Sustrans Route 4 to take a look at the castle. Only a short diversion

The memorial at the Castle celebrates Gwenllian, one of Wales's greatest heroines. In 1136 she led a Welsh army against Marcher lord Maurice de Londres. The battle took place nearby and despite her bravery Gwenllian was captured and beheaded. Gwenllian was a princess by birth and marriage. Her husband, Gruffudd ap Rhys, was prince of Deheubarth; her father, Gruffudd ap Cynan, Prince of Gwynedd. King Henry I died in 1135. With no heir, England was left in turmoil. Sensing the chance to win back lands, the Welsh launched a campaign against Anglo Norman rule. Gruffudd travelled to Gwynedd to gather support. With her husband away, Gwenllian led her doomed army against a Norman counter attack. Gwenllian and Gruffudd's greatest legacy was their youngest son, The Lord Rhys, who rose to become the most important Welsh ruler of the time.

Anyone who cycles to the Garden can, on handing in their helmets for safe keeping, get into the Garden for half price (based on the adult ticket price). The Carmarthen-Llanelli loop on the National Cycle Network route 47, goes past the entrance of The National Botanic Garden of Wales, known as the Celtic Trail.

The height of the summit from sea level is 284 meters (932 ft). You will have enjoyed some sustained climbing and steep grades by the time you get here! But you're rewarded with some fine views.
