A group of us have been going to Betws Y Coed for our annual pilgrimage for the last 5 years. We book and stay at Swallow Falls Hostel. £24pppn and that includes breakfast. Not sure if they have rooms for two, but worth checking. Also can give this place a try http://www.thevagabond.co.uk If you stay I can highly recommend food in the evening from the Stable bar which is part of the Royal Oak.
Rides. I have rode the first section of Penmachno and is my favourite trail. We are heading up later this year to do the full trail.the second half has had some work on it and looks mint…
Llandegla is not to far maybe worth a look.
There is also a lop that passes by Swallow Falls hostel, Sarn Helen or Sarn helens revenge, it’s part of the old roman road. this is one we are also going to do when we head up.
Hope this helps..
