Hillforts in Dwyfor and Merioneth

This guide provides information on the location of and access to the main Iron Age hillforts in Meirionnydd, all but one of which lie within the Snowdonia National Park. It also provides a description of the main features of each fort that can be seen by a visitor. It is designed for the average interested visitor and does not presume a previous knowledge of archaeology. There are more forts than are listed here but those not included are on private land and are not accessible or of less visual value. Please read the notes for visitors, below.


All these forts are protected as Scheduled Ancient Monuments and it is illegal to disturb them in any way or to carry out metal detecting over them. Do not walk over the stone parts of the structures, which can be damaged by trampling.

An Ordnance Survey map is needed to make use of the guide. This would preferably be the Explorer 1:2500 maps OL18 and OL23.


Be safe – plan ahead and follow any signs
Leave gates and property as you find them
Protect plants and animals, and take your litter home
Keep dogs under close control
Consider other people
