South Stack Heritage Group (Ynys Lawd) was formed in 2017 to ensure that the South Stack lighthose and island were open to the public during the year.
The group is a not for profit organisation, and will emply up to 6 people during the season to give guided tours around the lighthouse.
The group are also happy to arrange evening visits for groups, schools etc
South Stack is famous as the location of one of Wales' most spectacular lighthouses, South Stack Lighthouse. It has a height of 41 metres (135 feet). It has a maximum area of 7 acres.
Until 1828 when an iron suspension bridge was built, the only means of crossing the deep water channel on to the island was in a basket which was suspended on a hemp cable. The suspension bridge was replaced in 1964, but by 1983 the bridge had to be closed to the public, due to safety reasons. A new aluminium bridge was built and the lighthouse was reopened for public visits in 1997. Thousands of people flock to the lighthouse every year, thanks to the continued public transport service from Holyhead's town centre.
There are over 400 stone steps down to the footbridge (and not, as local legend suggests, 365), and the descent and ascent provide an opportunity to see some of the 8,000 nesting birds that line the cliffs during the breeding season. The cliffs are part of the RSPB South Stack Cliffs bird reserve, with a visitor centre, and bird hide at Elin's Tower. The tower provides a place to see Choughs, Peregrine falcon, Kestrel and various marine mammals like the Harbour porpoise seen at high tide, Grey seal, Risso's dolphin and Bottlenose dolphin.
The Anglesey Coastal Path passes South Stack, as does the Cybi Circular Walk. The latter has long and short variants; the short walk is 4 miles long and takes around two hours to complete. Travelling from the Breakwater Country Park, other sites along the way are the North Stack Fog Signal station, Caer y Tŵr, Holyhead Mountain and Tŷ Mawr Hut Circles.
The South Stack Formation was chosen as one of the top 100 geosites in the United Kingdom by the Geological Society of London, for its display of small-scale folding
