The walk you did is one I have always wanted to do, where do you start please, and are there any maps that show the route?
Martin, You start the walk from where the Golfers cross the road at Maesdu Golf Club and you will see the public footpath sign. Here's a brief description of the route:-
Cross the stile and follow the path on the right by the houses. At the last house cross the stile on the right and keep to the path following the wall and at the end of the scrub on your left, keep going left until you reach the base of the hill then go up to the Watchtower.
Retrace your steps to the field but don’t go through the farmyard, but take the stile on the right and then the next stile ahead of you. Turn right and keep along the hedge on the right until you reach the Church.
After you’ve had a look around there, cross back over and go into the cul de sac Cae Mor and follow the footpath to St Mary’s well then make your way to Bryn Lupus Road and turn right.
I would suggest that you keep on the road until you come to Maes Castell and then at the top of the road go through the public footpath to the Castle
As I've said before, try and keep this for a Summer walk as the ground is very wet and deeply rutted and I wouldn't want you to damage that ankle again!
