Trigonos, Plas Baladeulyn
Nantlle, Caernarfon
Wales, LL54 6BW

Travelling to Trigonos
Trigonos is situated in the village of Nantlle on the B4418, between Penygroes and Rhyd Ddu. Caernarfon is the nearest town and Bangor the nearest mainline railway station (West Coast mainline)

By Road
We offer some routes for travelling by road because experience of using satnavs is very varied. Often the satnav takes you on a longer and slower route than is necessary and on roads that can be clogged in high summer and difficult in the midst of winter.

From the North
Take the A55 toward Bangor/Holyhead. Ignore the first junction signposted to Bangor and leave at the following junction, signposted Caernarfon & Bangor. Follow signs for A487 to Caernarfon and then Porthmadog. About 5 miles beyond Caernarfon, at a roundabout, take the first exit, signposted Penygroes. In Penygroes, turn left just after the traffic lights at the crossroads, signposted to Nantlle. After 150 yards turn right at the T junction and continue for 1.5 miles. At the next T junction turn right to Nantlle/Beddgelert and carry on for 2 miles into the village of Nantlle. The entrance to Trigonos is on the right and well signposted.

From South & Mid-Wales
Follow the A470 through Dolgellau and then the A487 towards Caernarfon. About 5 miles before Caernarfon take the third exit at a roundabout, signposted Penygroes. After 200 yards, at the next roundabout, take the first exit. After quarter of a mile turn right at the crossroads just before a set of pedestrian lights (signposted to Nantlle). Continue as above.

From the Midlands and South of England
There are many possible routes, some more scenic than others.
M54 on to the A5. Follow to Bangor, then join the North route (A487 to Caernrafon) above
M54 on to A5 up to Capel Curig. Left onto A4086 / A498 to Beddgelert. Then A4085 to Rhyd Ddu and left onto the B4418 to Nantlle. Drive through the first part of Nantlle and after 200 yards of open land, turn left into the Trigonos driveway. Please note that this is a scenic but high level route and may be difficult in poor conditions.
