Update 7 December 2012: Google have now updated their mapping to show the correct layout of the local roads, but unfortunately have not labelled the map with the name of our lane. I don’t know when or whether this may happen, or whether the TeleAtlas data is more complete. If anyone has updated their SatNav database recently, perhaps you could let us know whether “Lon Tyddyn Agnes” is featured on it — we don’t have a SatNav and have no plans to get one. A delivery driver still found his way to Tan Yr Allt using his SatNav recently, so I’m guessing it’s still not right… But at least the locals now know where we are (even if they’re getting tired of giving directions).
Update, 15 November 2011: I have been notified by TeleAtlas, who provide the mapping data for SatNavs etc., that they have updated their information for our location. Hopefully this means that your SatNav will soon be capable of bringing you to our gate rather than some random slate quarry.
The council have now installed our new street name plate, and very fine it looks too.

So our “official” address is now:
Cae Mawr B&B
Lôn Tyddyn Agnes
Llanllyfni
Gwynedd
LL54 6RT
However, it may be a little while before SatNav starts working properly. So please look carefully at our directions page on the website when visiting, or you may still find yourself in a quarry!
As you go up the hill, look out for our smart new hanging sign on the gatepost by the lane:
