Beautiful hike, too bad it was cloudy at the top. 12.3 km isn't the actual distance you'll be hiking: it's definitely 10 km more because you can't walk a straight line on this path. It's very busy on this trail; there's a queue to reach the top.

Segontium Romon Fort is an impressive excavated fortification located just outside Caernarfon. It was founded by Agricola in AD77, and it was garrisoned for over three hundred years. It was the longest-held Roman fort in Wales and used to hold a 'cohors milliaria,' a regiment of about 1,000 auxiliary infantry, mainly recruited from Belgium and Germany. It was linked by Roman roads to the main legionary bases at Chester and Caerleon by a series of marching camps and other forts.

These echoed imperial Roman architecture, especially the walls of Constantinople. They also recalled the Welsh myth of Macsen Wledig, who dreamed of a great fort at the mouth of a river – ‘the fairest that man ever saw’. So Caernarfon is a castle of dreams. A legend brought to life. Even after 700 years it still stirs the imagination like no other Welsh castle.
