If your coming to the Rhinogs, then the best route i can suggest, is to do a round of the southern Rhinogs.
Approach Diffwys, from the Bwlch Y Rhiwgyr direction, or even better contact me a few day's before your arrival, and i will guide you around.
What we will have to find out, is how we can safely exchange contact details.
Living in Dyffryn, a mobile phone is almost useless, so i do not own one, so if the forum moderator can give us permission to exchange contact details, i will promise to meet you at an agree time.
Once i have made arrangements, i keep to my word, and its far better to do the Rhinogs in the company of someone who has done them a few times.
Once you know exactly when you will be arriving in the Dyffryn area, we will arrange to meet.
Or even better, tell me the make and model of your car, and give me some idea when you will be in the Dyffryn Ardudwy area.
A good meeting location would be outside Foxes post office and general store.
Not knowing the area, it would be tricky for you to find the best parking place and route.
I know exactly where to go, and as ive not had the company of a fellow South Walian walker for ages, it would be a pleasure to show you around
