Llywelyn the Great · Wales's most powerful native prince, whose keep this was
Worth the trip
The approach itself, walking up through farmland with the keep rising against the sky - reviewers call it one of the most atmospheric castle approaches in Wales.
Before you go
There's no parking at the castle - use the layby further along the road - and you'll cross a farm gate (close it behind you); check the Fri-Sun seasonal interior opening before counting on getting inside.
What visitors say
Dolwyddelan Castle reviews · 4.3 / 5 across 398 Google reviews
Reviewers describe Dolwyddelan as an atmospheric and rewarding castle to walk up to, with several enjoying the countryside views and the small waterfall along the path.
A recurring practical point is that the keep interior is only open Friday to Sunday between April and September, so a couple of visitors arrived to find it locked; most seem aware of this in advance and are not put off, still finding the walk and exterior worth the trip.
“Great castle lovely walk up to it doesnt take long fantastic views across the valley. Wasn't open when we went but knew that before we walked up.”- paul marsden, visitor review
History
Llywelyn ab Iorwerth · 1210-1240
Llywelyn ab Iorwerth (Llywelyn the Great), ruler of Gwynedd, probably built this castle between 1210 and 1240 to guard an east-west mountain route. Edward I captured it in 1283 and immediately refortified it. The castle declined in military importance thereafter, and was restored in the mid-19th century by Lord Willoughby de Eresby.
