Fairy Glen is a secluded gorge and beauty spot on the Conwy River.
It's just off the A470, near the intersection with the A5 - there is a small car park nearby - turn left just after the Fairy Glen Hotel (but not into the hotel car park!), and it's reached down a small track. You then have to walk for about 15 minutes to get to Fairy Glen itself.
There is a small admission fee of 50p per person to cover maintenance of the footpaths.
After around 10 minutes on the footpath, the glen is reached by descending some stairs. Be warned that they are steep in places (and slippy in the wet), and therefore not suitable for everyone - good hiking boots are recommended. We visited on New Years Eve and only saw 2 other people there, which added to the experience.
The view is amazing and you can get some great photos and videos here. It's well worth a visit.
