Tynllwyn is a four-star caravan, camping, and touring park set in the hamlet of Rhydyronen in southern Snowdonia, overlooking the Dysynni Valley. The site lies about 2. 5 miles from the seaside town of Tywyn and roughly seven miles from Aberdyfi.

Surrounded by hills and open countryside, it draws walkers, birdwatchers, cyclists, and anglers, with streams, rivers, lakes, and sea fishing all within easy reach.

The Talyllyn Narrow Gauge Railway runs alongside the park, with Rhydyronen Station just 50 yards away, offering rides west to Tywyn or east toward Dolgoch Falls, Abergynolwyn, and the wooded valley of Nant Gwernol.

The park offers grass pitches for tents and touring caravans, hardstanding pitches with electric hook-ups, a modern toilet block, a children's play area, and a selection of static caravans available for hire.

The site is open from 1 March to 31 October and welcomes pets.
