Bryn Euryn – A Walk With a View!

Bryn Euryn is a limestone mountain 130 meters high with a Site of Special Scientific Interest, a trig point at the summit and is home to the ruins of Llys Euryn, a house built in the mid 1200’s.

Its a great walk to the top, with 360 views of Rhos On Sea, colony bay and Mochdre, and off in the distance Llandudno, up the Conwy Valley and across to Llandulas and beyond.

There is a large, busy allotment at the foot of the hill along with large fields popular with dog walkers. Theres lots of wooded ares and nice walks circling the Bryn, and loads of spots for great views of Rhos Village.

We have a great aerial video almost finished to show off The Bryn, check back soon!


Heres some info from the Conwy Council leaflet about Bryn Euryn:



Beautiful butterflies, fabulous flowers, a historical hillfort and a magni cent ruined mansion are some of the delights of Bryn Euryn, which can be sampled on the Summit and Woodland Trails within this lea et. Bryn Euryn is managed by Conwy Countryside Service as a Local Nature Reserve. We hope you enjoy your visit to the hill.

This waymarked circular trail leads you past the ruined mansion of Llys Euryn, through woodland and grassland, to the ancient hillfort at the summit, with its panoramic views, and back to the starting point of the car park.The trail is about a mile in length and does have some steep climbs/descents which can be slippery after rain, so you will need stout footwear. Follow the green waymarkers from the car park entrance.


The Summit Trail takes you by the fourteenth century mansion of Llys Euryn, once celebrated in bardic verse.
It also leads you to a sixth century hillfort at the summit of Bryn Euryn, with its panoramic views.The summit was also used by the RAF during the war.The history of both sites is detailed on boards located on site. Even 200 years ago Bryn Euryn was surrounded by countryside with small hamlets at Mochdre, Rhos, Llysfaen and Colwyn but it is now an island amongst housing. On the hill itself, it is interesting to note that the summit of the hill was clear of scrub in 1948 but is now covered in blackthorn.

This waymarked circular trail initially follows the Summit Trail, then continues through woodland, with fewer climbs/descents, and back to the starting point of the car park.This trail is about 1.5 miles in length. Follow the red waymarkers from the car park entrance.


Bryn Euryn has a rich variety of wild flowers both in the grassland and woodland, which love the lime rich soil here.The grassland areas are valuable enough to have been designated a Site of Special Scienti c Interest and the whole hill has been declared a Local Nature Reserve in recognition of its great wildlife and community value.

The woodland flowers are best seen in the spring and include wood anemone, dog’s mercury, wood sorrel and wood avens. In the damper parts of the wood the attractive hart’s tongue fern is abundant.The grassland areas bloom through the summer -except for the spring cowslips- and characteristic species include common rockrose, kidney vetch, lady’s bedstraw, carline thistle and wild thyme. Where the rock lies near the surface the nationally scarce hoary rockrose and Nottingham catch y can be found. Several orchids are to be found including early purple orchid, pyramidal orchid, and green winged orchid. An interesting plant which has not recently been found on the hill, is ivy broomrape. It has no green colouring and is parasitic on the roots of ivy.There are also some uncommon shrubs and trees on the hill, such as spindle, yew, juniper and spurge laurel.


The flowers support a great variety of insect life. Twenty six species of butter y have been recorded on the hill. In the woods you will notice the speckled wood. On the rocky areas you will see the wall brown and grayling. Flying among the grasses you may see the meadow brown and small heath, while on the bramble and gorse the gatekeeper may be found. Near the summit in May and June you may nd red admirals and painted ladies, which have migrated from Central Europe and North Africa. Other colourful nds include the peacock, small tortoiseshell, small copper and the common blue. A day ying moth you may see in the summer is the handsome six spot burnet moth. It has dark green wings spotted with red but it becomes a crimson blur when it ies. Its caterpillar feeds on the abundant bird’s foot trefoil and then its characteristic pale yellow cocoons can be found on the stems of plants.


Think of tropical seas and coral reefs! These were the conditions 350 million years ago when the limestone from which Bryn Euryn is composed was formed from the accumulated and compressed remains of sea creatures. Volcanic activity and earth movements then buckled the limestone and incorporated mineral veins into the rock. More recently, some 12,000 years ago in the last Ice Age, huge glaciers scoured out the softer rocks and left the valleys around Bryn Euryn and the steep cliffs on the southern side.
