Holiday-planning question

[fivemack]

I've just watched a rather impressive programme about Caernafon castle, and am pondering doing something castle-based on a bike over one of the Bank Holidays (late May probably - might well want to go to Spain and avunc for the other one) this year.

It looks as if you can leave Cambridge Friday afternoon and get to Conwy (London, walk across to Euston, Chester, Conwy) late Friday evening; the three castles Conwy .. Beaumarais .. Caernafon seems possible on the Saturday unless they're sufficiently awesome that you can't fit three castles and 60k flattish cycling into a day. Caernafon to Harlech over Beddgelert looks good (if knee-eating) fun on the Sunday morning ... what's the next stop after that? To Machynlleth in the evening, see the Centre for Alternative Technology Monday morning and then afternoon train through to Cambridge, or is there another castle practically available?

Am I missing something critical which would make this either unexpectedly more awesome than it looks, or completely miserable?

The Britannia Bridge appears to be forbidden to bicycles

I am kind of pleased to know that, as it is very narrow and busy and I find it scary enough trying to get across it in a car. But still, rah, cyclists have a right to scary bridges too, rah.
