The Narrow Gauge Railway Museum

The Narrow Gauge Railway Museum at Wharf Station in Tywyn is a proper indoor museum dedicated to the history and engineering of narrow gauge railways and dogs are genuinely welcome inside the galleries alongside you. It's paired with the Talyllyn Railway, making it a real day-out destination rather than just a walk with a heritage backdrop. The museum opens at 10:00 on days when the Talyllyn Railway is running a public service, so it's worth checking the railway timetable before you set off.

Admission is free, with donation boxes available if you'd like to contribute. Dogs can explore the museum galleries and visitor spaces with you and there are no special restrictions mentioned in the official leaflet.

Parking is at the Talyllyn Railway car park, a short walk from Wharf Station. It's a manageable day trip from Barmouth and the combination of museum and railway means you can plan a full morning or afternoon without leaving your dog behind or confined to outdoor waiting.
