If you want to park here, you have to reserve a parking space in advance for 20 GBP. We didn't manage to do it, as everything was fully booked. You can then park in Llanberies and take the Sherpa Bus S1 or S2 to Pen y Pass. The bus runs every half hour. From Pen y Pass, you can then choose the Miner's Track or Pyg Track. Have fun!

Currently parking is pre-booking only! All others are directed to the P+R in the village and need to get up by bus or walk.

It's well worth the effort to climb to the top of the pass.

Magnificent and dizzying view! However, prefer to go around in the opposite direction to that indicated. The steep slope is very narrow and steep. Easier to go up than to go down.

Sychnant Pass (Welsh: Bwlch Sychnant, "Dry-stream Pass") in Conwy County Borough, Wales, links Conwy to Penmaenmawr via Dwygyfylchi. Much of the pass is in Snowdonia National Park, and a large area of land within it has been designated a site of Special Scientific Interest. At the bottom is the village of Capelulo, which lends its name to the community of Penmaenmawr. Tough climb from any direction. Well worth for the stunning scenery.

It follows a former Roman road and is marked by two large, prehistoric monoliths at its highest point. The pass also served as an ancient drovers' road and is surrounded by other prehistoric sites like a stone circle and cromlech, offering a tangible connection to thousands of years of human history within the wild Carneddau landscape.
