The keep of Llywelyn the Great, Wales's most powerful native prince, set on a rocky outcrop in the Lledr Valley - free to view from outside, though the interior only opens seasonally, Friday to Sunday.
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.
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.
