That's a beautiful part of Europe to be having a holiday at Gwynant, hope that you enjoyed your holiday over there. It's over 40 years since I went on the Brenner Pass when we were staying at Seefeld but I remember the scenery very well. We've also enjoyed the Dolomites when we stayed at Riva Del Garda at the northern end of Lake Garda.
Back to reality now and Llangefni, did you go on that boardwalk? I was very impressed with it and the area in general, the boardwalk must have cost a packet to erect but lots of families were enjoying walking on it.
There has been talk of reopening the railway line from Llangefni to Amlwch but that will be expensive and I'm not sure if it would be viable either,
