Hi Mike
Paddling in Wales can definitely have it's moments. I live on Anglesey and still find I have not got bored with paddling ion my 'doorstep' yet.
A few ideas :
The trip for Aberdaron (on the end of the Lleyn peninsula) to Bardsey Island is worthwhile. Bardsey contains a few houses, lighthouse, lots of seals, no electricity etc. The crossing of Bardsey Sound (about 50-60 mins) needs some good planning with 6kt tides on springs but you can pick the tide up, get to the island to have lunch and then continue up the north Lleyn coast. Recommend getting out at Porth Oer (Whistling Sands - they squeek more than whistle!) - from there you can jog back to Aberdaron for the car ( if you have no shuttle). Don't paddle the sound in bad weather!
Anglesey Circumnavigation as a whole makes a satisfying trip, can be done in about 14hrs paddling, though makes a much more enjoyable trip in 3-4 days. Plenty of 'quiet' beaches to sleep on.
Anglesey north coast has quite an impressive coastline, 6kt tides and a number of overfalls/tide races.
Skerries - off lying rocky islands from North Anglesey - can paddle with ebb tide from Cemlyn Bay - visit island (Lighthouse, sheltered lagoon, surfable tide race, Puffins, Seals, Terns - by the millions!), have lunch and return to Cemlyn on flood tide.
The Stacks - South & North Stacks on North West Anglesey, committing trip but impressive scenery. Large overfalls on springs and plenty of sea birds in summer.
Penrhyn Mawr - S of South Stack - large overfall/race with eddies to return to waves.
Puffin Island - less than a mile off-shore but with a large colony of veryfriendly seals in the summer. Usually will have a few 'race' your boat as you paddle along the island and are VERY inquisitive as a whole.
Skomer Island 'near' St Davids - nature reserve with plenty of Puffins in the summer. Also The Bitches - not too far away for some good bouncy stuff and surfable waves.
And so it goes on...
