Snowdonia (Wales): Places to see?

Folks,

I am going across to Snowdonia this weekend. Anybody got any recomendations for places to see / walks to do / sights to photograph?

Thanks in advance,
Duncan

Well aside from Mt Snowdon, apparently the perpetual rain is quite a sight! And don't forget to keep your camera at the ready for a rare glimpse of a Cymru sheep while your there (just try to keep the farmer out of shot!). :D

Sorry, couldn't resist :) http://snowdonialtd.org/snowdonia/home.htm
