There are plenty of dramatic sheer cliffs on this section where coastal erosion is an obvious process. Every year Pembrokeshire is a little smaller than the year before and the route of the Coast Path has to be continually reviewed to ensure safety.

Pwllderi towards Penbwchdy 1 mile (1.6km)

The northern section is minor road (cul de sac). Magnificent views across Pwll Deri towards Strumble and Garn Fawr. Mostly a gentle graded section with a seat at the south end. A fairly steep slope, no stiles,  five steps and three gates. 

Walk Difficulty: Stiles or flights of steps or steep hills.

Walking Access Point
Garn Fawr Footpath
 (Grid ref: SM892397)
Footpath joins steeply up hill to Garn Fawr offers a series of circular walks including a ridge walk to Goodwick.

Worth a look
Garn Fawr and Tal-y-Gaer
 (Grid ref: SM894388)
Garn Fawr is an impressive Iron Age hill fort, with superb views from the top. The hill’s natural rocky outcrops are linked with walls of loose stone to form multiple defences. Beside the track leading to Tal-y-Gaer farm is a low corbelled ruin, which may be a hermit’s cell dating from the Middle Ages or earlier.

Aber Bach
 (Grid ref: SM883350)
Most of the year the small stream from inland trickles through the pebble bank. During storms or very wet weather the stream or the bank can be difficult to cross. In this case either wait for low tide or take the alternative road and footpath route around the valley.

The lower gate leads onto a short surfaced section to a viewpoint across Aber Mawr.

Aber Mawr and Aber Bach (Grid ref: SM882348)

Aber Mawr. Around 20,000 years ago, towards the end of the Ice Age, the advancing Irish Sea ice sheet deposited marine sediments at various places in north Pembrokeshire. These purplish-blue clays, known as Irish Sea till, can be seen between layers of stony clay at Aber Mawr. The shingle banks at Aber Bach and Aber Mawr are often said to have been created by a violent storm in 1859, but in fact were formed by gradual processes associated with rising sea levels after the end of the Ice Age. The storm was, however, responsible for the wreck of the sailing vessel Charles Holmes, lost with all hands just north of Aber Bach. The small building at Aber Mawr was the terminus for the first Atlantic submarine telegraph cable in 1873.

Aber Mawr Beach 
(Grid ref: SM881345)
Unspoilt wide sandy beach with a pebble bank. This is one of the fastest eroding parts of the Pembrokeshire Coast Path. Parts of the beach are moving inland at up to 1 metre each year.

Walking Access Point
Aber Mawr Paths 
(Grid ref: SM881344)

 (Grid ref: SM852336)
A sandy beach overlooked by the village. Also well used by the many boats including crab and lobster fishing boats and the local diving school.

 (Grid ref: SM85263364)
Abercastle is also known as Cwm Badau (Bay of Boats). For centuries, corn, butter and oats were exported from here to Bristol and Liverpool, while limestone and anthracite were imported. The lime kiln is still in good condition and the large ruined building was once a granary. In 1876, Alfred Johnston anchored his 20 foot boat Centennial here after completing the first solo trans-Atlantic voyage.

Walking Access Point

Returns to minor road, offers short cut to Trefin.

Cwm Badau Cliffs 
(Grid ref: SM850337)
Unguarded cliff edges. Keep to Path. Take care in windy weather. Long sections of Path fairly close to the cliff edge.

Worth a look

Porthgain to Gribinau Cliffs
 (Grid ref: SM816328)
Unguarded cliff edge. Keep to path. Take care in windy weather.

Porthgain (Grid ref: SM814325)

In the 19th and early 20th centuries, Porthgain was a thriving industrial port. The local stone, a hard igneous rock known as diorite, was quarried for use as a building stone and for surfacing roads. Crushed and graded, it was stored in the great hoppers which still loom over the harbour, before being exported by sea. There was also a brick-works which used local clay, and much of the slate quarried at Abereiddi was shipped from here. Trade declined after the First World War and the stone-works finally closed in 1932. The National Park Authority is now responsible for conserving the harbour and industrial remains. The Row, a terrace of cottages on the west side of the village, was re-roofed using Abereiddi slates recovered from a cargo which had sunk in the 19th century.

Porthgain Village
(Grid ref: SM815325)
The Sloop Inn –  one of the few pubs actually on the route of the Pembrokeshire Coast Path National Trail. Art galleries, restaurant and tea rooms.
