Porthmadog sits at the edge of the Glaslyn Estuary in Gwynedd. This town has deep roots in the trade of slate. My top tip is to walk along the Cob. You can see the steam trains of the Ffestiniog Railway puff past for free. It is a prime choice for a low cost day in the sun. The harbour was once a busy spot for tall ships. Now, you can watch the tide flood the sands. The views of the peaks of Eryri are clear across the water. The air is fresh and the streets have local shops. Many paths here are dogs welcome trails. Life here is calm and tied to the rails. It is a smart spot for a trip. Some stays offer a hot tub.
