The Dee, the Straits & the Mountains

Mountains, coast and the Dee Valley

3 Day Tour

Overview

The Dee, the Menai Strait and the mountains shape North Wales, and this tour gives each of them a day.

The Dee has Telford's aqueduct, 38 metres above the river. Across the strait, Anglesey's coast runs from the seabird cliffs at South Stack to a hillside turned red and purple by copper mining. And the mountains take you over Pen-y-Pass under Snowdon and down to the Llŷn.

It finishes on the sand at Morfa Nefyn, where the Ty Coch pub sits right on the beach.

What guests say

John Pritchard and Celticos is the Best!!!!

Three couples traveled to Northern Wales with John in June 2026. We had the time of our lives. For three days he kept each and every one of us not only happy but entralled. We had to work around some bad weather and he adjusted his schedule to make it work. His love for his country realy showed and his knowledge is impressive. When the group wanted to do two different things, he arranged everything. He had to pick 3 of us up at 6 am to climb Snowden, and then pick the rest up at 9 am. He gave great advice throughout the trip. We felt like we got to know the region much better with him as our quide. His enthusiasm and love for Wales are infectious. We traveled in his very nice travel Mercedes van each day and he had water ready for us.

I would whole-heartily recommend John.

John was an excellent tour guide and a really great guy. Our group of four spent three days touring northern Wales with him. He was always quick to respond to emails, picked us up promptly, very flexible, extremely informative about everywhere we went, and even had snacks! I highly recommend Celticos and John!

Frequently asked questions

Can we change the itinerary?

Yes. Every tour we run is customised, so treat this itinerary as a starting point. Tell us what interests you and we will build the days around it.

Can this tour be combined with other tours, or made longer or shorter?

Yes. A day tour can be built into a multi-day tour, and a multi-day tour can be shortened, extended or joined to another. Tell us how many days you have and we will plan around them.

Are admission fees included?

No. Entry to castles, gardens and other attractions is paid on the day, where a fee applies. Many of the castles are cared for by Cadw, and we can advise on the best-value tickets when you book.

Is food included?

No. As we tour we will suggest eating places that our guests have enjoyed.

What should we wear and bring?

Sensible footwear for some light walking, and a rain jacket, just in case.

How much walking is involved?

Some, and none of it strenuous: the walk from the car to a castle gate or a viewpoint. If walking is a concern, tell us and we will plan the stops accordingly.

Where should we stay?

Somewhere central, so that touring time is not spent driving to the start. Our accommodation advice lists places our guests have used, and we are happy to suggest a base for your tour.
