Can anyone reccommend some riding stables in Snowdonia?

My girlfriends birthday is coming up and I'm looking to treat her to a day horse riding somewhere a bit more scenic than sunny Nottinghamshire.

Can anyone recommend anywhere, or even better does anyone off here run anywhere?

She is very experienced and rides 2 or 3 days a week at present. I just know she would love to go for a days riding in the mountains.

Before anyone says it, I have googled it, I have called a couple with no response so followed the call up with an email with no reply either. Which is a shame as some of them look quite good.
