An engine from the quarry
The little steam locomotives were rescued from the same Dinorwic quarries whose slate this line carried to the coast from the 1840s.

Know this before you plan around it: for the whole of 2026 the Llanberis Lake Railway is not running along the lake at all. The company has handed most of its trackbed to National Grid for a cable-replacement job under the line, and the famous five-mile return run beside Llyn Padarn has shrunk to a half-mile shuttle between the main station in Padarn Country Park and Llanberis station. Fifteen minutes there and back, £2 an adult, £1 a child, and the ticket is good for unlimited rides that day. The official site says plainly that full lakeside journeys resume in 2027. What is left is still a real steam engine, a small one rescued from the Dinorwic slate quarries where it worked more than a century ago, now fired up to haul open carriages along a route that carried slate to the coast from the 1840s. For small children that alone is the outing: the whistle, the smoke, the wooden benches. For adults it is a pleasant quarter of an hour and no more, and the view across Llyn Padarn to the thirteenth-century stones of Dolbadarn Castle is free from the shore anyway. The practical advice is not to make the train the reason for the drive but a cheap add-on to a day in Llanberis, with one warning. The National Slate Museum beside the station, long the obvious pairing, has been closed since November 2024 for a redevelopment with no reopening date announced. What is still there costs nothing and is good: flat lakeside paths that take a pushchair without fuss, woodland trails, and the Quarry Hospital Museum in the same park. If reaching the summit of Snowdon is the goal, the pricier and longer Snowdon Mountain Railway is across the road and needs booking weeks ahead in summer. Getting here from the heart of Snowdonia is easy: about 30 minutes by car from Betws-y-Coed over the Pen-y-Pass on the A4086, roughly 20 minutes from Caernarfon or Bangor, with pay-and-display parking in Padarn Country Park at the station entrance. In 2026 trains run on selected dates between 15 February and 5 November, daily through August and the school holidays, otherwise mostly Tuesday to Thursday plus Sundays, and barely at all in May outside the half-term week, with six departures a day between 11:00 and 15:00, so check the calendar before setting off.

Flat lakeside and woodland trails run right through Padarn Country Park, and Dolbadarn Castle is a short walk away at no charge.
No queues, no advance booking and no altitude, which makes it the easy choice with toddlers when mountain tickets are gone.

Not on its own this year: fifteen minutes on half a mile for £2 is a treat for children, not a sightseeing ride, and the National Slate Museum next door, the usual companion outing, has been shut for redevelopment since November 2024. Pair it instead with a walk along the shore and Dolbadarn Castle, or wait until 2027 when the full run to Penllyn and its view of Snowdon comes back.
The mountain train climbs to near the summit on a trip of about two and a half hours, costs from £45 an adult on the diesel service and over £60 on the steam one, and sells out weeks ahead in summer; the lake railway is flat, short, cheap and bought on the day. With under-fives, or on a cloudy day that hides the summit, the lake train is the gentler and far cheaper choice.
