See the Last Invasion Tapestry in Fishguard town hall

Stand in the Royal Oak, where the surrender was negotiated

Find Jemima Nicholas's memorial stone in St Mary's churchyard

Walk down to Lower Town harbour below the bridge

On 22 February 1797 a French force landed near Fishguard — the most recent landing on British soil by a hostile foreign power — and two days later, after surrender talks at the Royal Oak in the square, laid down their arms on Goodwick Sands. Jemima Nicholas, who is said to have rounded up a dozen of them with a pitchfork, has a memorial stone in St Mary's churchyard, and a tapestry made in 1997 for the bicentenary tells the whole story in the town hall.

Fishguard and the Preseli

Nine nights on the Pembrokeshire coast from Tenby to Cardigan: Caldey's monks and St Govan's cliff chapel, Skomer's puffins and shearwaters, the coast path from St Davids to Solva, and the Neolithic dolmen at Pentre Ifan.

Pembrokeshire: Tenby to St Davids and the Teifi

Stand under the capstone of Pentre Ifan, balanced on three stone tips

Find the portal stones and the stone that seems to block the entrance

Go into the rebuilt roundhouses at Castell Henllys

Find out how the roundhouses were rebuilt on their original Iron Age foundations

Pentre Ifan, above Nevern in north Pembrokeshire, is the largest and best preserved Neolithic dolmen in Wales. Its capstone, five metres long, is thought to weigh 16 tonnes and rests on the tips of three uprights two and a half metres off the ground; it was raised around 3500 BC, traditionally as a communal burial. A few kilometres away, Castell Henllys is an Iron Age hillfort where four roundhouses and a granary have been rebuilt on their original foundations, some 2,000 years old — the only place in Britain where that has been done.

Walk the Pembrokeshire Coast Path north from Abereiddy to Porthgain, on the 186-mile National Trail from Amroth to St Dogmaels, opened on 16 May 1970

See the Blue Lagoon at Abereiddy, the flooded slate quarry about 25m deep where the Red Bull Cliff Diving World Series jumped from 27m in 2012, 2013 and 2016

Look for Ordovician graptolite fossils in the shale beds of Abereiddy beach

The Pembrokeshire Coast Path, a National Trail opened on 16 May 1970, runs 186 miles from Amroth to St Dogmaels, . At Abereiddy a flooded slate quarry, the Blue Lagoon, is about 25m deep; the Red Bull Cliff Diving World Series jumped from 27m in 2012, 2013 and 2016; the shale on the beach holds Ordovician graptolite fossils. North along the path from Abereiddy is the old slate and brick harbour of Porthgain.

Visit St Davids Cathedral in Britain's smallest city by population, its present building begun in 1181, and see its sloping nave, the Irish oak ceiling of 1530–1540 and the restored Shrine of St David re-dedicated in 2012

Explore the ruins of the Bishop's Palace beside the cathedral

Take a boat trip from St Justinian's lifeboat station to Ramsey Island, the RSPB reserve where more than 400 grey seal pups are born each autumn, sailing from Easter to October

St Davids is Britain's smallest city by population. Its cathedral was begun in 1181: the nave slopes, the ceiling is Irish oak from 1530–40, and the Shrine of St David was restored and re-dedicated in 2012. Beside it are the ruins of the Bishop's Palace. From St Justinian's, boats cross to Ramsey Island between Easter and October; it is an RSPB reserve, and more than 400 grey seal pups are born on its beaches each autumn.

Visit Cardigan Castle and the eisteddfod story

Watch the falls at Cenarth from the 1787 bridge

See the coracles at the National Coracle Centre

Walk the Teifi estuary path below the town

Rhys ap Gruffydd took Cardigan Castle in 1166, rebuilt it in stone in 1171, and held the first recorded eisteddfod there in 1176; the Teifi runs past it to the sea. Six miles upstream at Cenarth the river drops over falls beside an old water mill that now holds the National Coracle Centre, and the bridge of 1787 was built by William Edwards and his son David.

Book a guided coasteering session on the St Davids cliffs

Swim through a zawn or sea cave on the traverse

Make a cliff jump into deep water with your guide

Surf or swim at Whitesands Bay afterwards

Coasteering — scrambling, swimming and jumping your way along a rocky coast instead of walking above it — was named by Edward C Pyatt, who put together 'mountaineering' and 'coast', and the word was in print by 1973. Andy Middleton took the word up in Wales in 1985 and in the late 1980s built it into a guided business from the Twr-y-Felin outdoor centre, working the cliff coast at St Davids. It spread from here to Cornwall, Anglesey and the Highlands, and Pembrokeshire is still where people come to do it.

Walk round the castle from Gerald de Windsor's keep to Perrot's Elizabethan range

Go into the Carew Tidal Mill, the only restored tidal mill in Wales

Carew Castle stands on a limestone bluff over the Carew inlet of the Milford Haven waterway. Gerald de Windsor built its first stone keep around 1100, on the manor that came to him with his wife, Nest, princess of Deheubarth. Rhys ap Thomas, who made his fortune by changing sides to back Henry VII just before Bosworth, held it later, and Sir John Perrot, Lord Deputy of Ireland, who acquired it in 1558, rebuilt the north walls as a long Elizabethan range of rooms — before falling from favour and dying in the Tower in 1592. Beside the castle is Carew Tidal Mill, the only restored tidal mill in Wales.

Walk the Great Glasshouse and its Mediterranean planting

Walk the double walled garden and the Regency lakes

The National Botanic Garden of Wales opened on 24 May 2000 on the old Middleton estate, and its centrepiece is Norman Foster's Great Glasshouse — billed as the largest single-span glasshouse in the world, about 99m by 55m — holding the plants of the Mediterranean climates. Carmarthen, a few miles west, has the remains of a Roman amphitheatre and one of the oldest markets in Wales.

Visit the Boathouse where Thomas lived and worked

Look into the writing shed on the cliff path

Find Thomas's grave in St Martin's churchyard

Dylan Thomas lived at Laugharne from 1949 until his death in 1953 and called it a 'timeless, mild, beguiling island of a town'; it is generally taken as the model for Llareggub in Under Milk Wood. The Boathouse above the estuary is now a museum, with his writing shed on the cliff path beside it, and the castle stands over the water, with the garden gazebo beside it where Thomas also wrote.
