Parking in a housing estate in Tongwynlais puts you right at the bottom of a well-walked footpath that takes you into the summit field. At this point you have to walk through tall grass to the trig point, which didn’t look that well visited. Views South are limited by a small treeline, which is disappointing as this is one of the highest points this close to Cardiff so those views would have been good.
A good little walk with a decent amount of ascent and views North are decent enough.
