Short break from Ireland to Chester, Conwy and Llandudno advice

[palrano]

Hello,

I'm in Ireland and am unable to fly due to illness, but I need a little break. I am hoping to take the ferry to Holyhead on sail and rail and spend a couple of days in Chester and another few days around Conwy (to see the castle!) and Llandudno to be by the sea.... I will be with my partner. We are both in our sixties now. But very young at heart!

I am ok walking, but not mad distances and it needs to be relatively flat. I see Snowdon is not too far away, and if the train is running I'd take that up and back. Is that doable, and if so where is the best starting point?

Is there anywhere I am missing out on, and are the above destinations ok for a short trip.

Thank you so much.

We stayed near Llandudno and Conwy last year and very much enjoyed the latter in particular - apart from the castle it’s a really lovely little walled town, there’s nice walk out along the coast and also there is an extremely interesting Elizabethan town house, Plas Mawr

We went to a nice restaurant called Dylan’s which did good seafood.

There is also an rspb reserve just the other side of the river which we enjoyed though I’m not sure how easy it’d be to get to without a car.

There is also a Theatre in Llandudno.
