About
Perched on a tiny island connected to Holy Island by a suspension bridge, South Stack Lighthouse (1809) is one of the most dramatically positioned lighthouses in Britain — 400 steps down a cliff face, with the sea surging through the channel below. The surrounding RSPB reserve protects the largest puffin colony on Anglesey, visible from April to July from Ellin's Tower seabird centre, along with choughs, peregrine falcons, and guillemots nesting in the cliff crevices. The views back towards Holy Mountain and across to Ireland are extraordinary.

Frequently asked questions
When can I see puffins at South Stack?
Puffins nest on the cliffs from approximately April to July. The peak viewing period is May and June when birds are most active on the cliff ledges. Bring binoculars — Ellin's Tower has telescopes set up during the season.
Do I need to pay to visit South Stack?
The RSPB cliffside reserve and Ellin's Tower seabird centre are free. Descending the 400 steps to the lighthouse costs £10 for adults and £5 for children. Buy your lighthouse ticket at the RSPB café at the top — there is no card payment or phone signal at the bottom.
Is South Stack suitable for young children?
The cliffside viewpoint and RSPB area are suitable for families with children of all ages. The 400 steps to the lighthouse are steep and exposed — not recommended for very young children or those who are not steady on their feet. The views from the top are almost as dramatic as from the bottom.
Are the 400 steps to the lighthouse difficult?
Yes — 400 steps of steep descent, then 400 back up. Most reasonably fit adults manage it in 15–20 minutes each way. Wear sturdy footwear. Steps are slippery after rain. Those with vertigo should note the steps are exposed to the sea below.
