The Pembrokeshire coastline includes numerous bays and sandy beaches. The [[Pembrokeshire Coast National Park]], the only park in the UK established primarily because of its coastline,<ref name="VWExploring"/><ref name="NatGeo2Nov2017"/> occupies more than a third of the county. The park contains the [[Pembrokeshire Coast Path]], a near-continuous {{convert|186|mi|adj=on}} [[long-distance trail]] from [[Amroth, Pembrokeshire|Amroth]], by the Carmarthenshire border in the southeast, to [[St Dogmaels]] just down the [[River Teifi]] [[estuary]] from [[Cardigan, Ceredigion]], in the north.<ref name="NTPembsCoastPath"/> The [[National Trust]] owns {{convert|60|mi}} of Pembrokeshire's coast.<ref name="BBCNews27Jan2018"/> Nowhere in the county is more than {{convert|10|mi}} from tidal water. The large estuary and natural harbour of [[Milford Haven (harbour)|Milford Haven]] cuts deep into the coast; this inlet is formed by the [[confluence]] of the Western [[River Cleddau|Cleddau]] (which flows through Haverfordwest), the Eastern Cleddau, and rivers Cresswell<ref name="PCNPACresswell"/> and Carew. Since 1975, the estuary has been bridged by the [[Cleddau Bridge]],<ref name="Hansard8Dec1994"/> a toll bridge carrying the [[A477 road|A477]] between Neyland and Pembroke Dock. Large bays are Newport Bay, Fishguard Bay, [[St Bride's Bay]] and western [[Carmarthen Bay]]. There are several small islands off the Pembrokeshire coast, the largest of which are [[Ramsey Island|Ramsey]], [[Grassholm Island|Grassholm]], [[Skokholm Island|Skokholm]], [[Skomer Island|Skomer]] and [[Caldey Island|Caldey]].<ref name="PCNPAIslands"/> The seas around Skomer and Skokholm, and some other areas off the Pembrokeshire coast are [[Marine protected area]]s.<ref name="DEFRAIslands"/>

There are many known shipwrecks off the Pembrokeshire coast with many more undiscovered.<ref name="BBCNews26Oct2014"/><ref name="DiveWrecks"/> A [[Viking]] wreck off [[Smalls Lighthouse|The Smalls]] has protected status.<ref name="WO6Jan2018"/> The county has five [[List of RNLI stations#Wales,_West_&_Isle_of_Man_Region|lifeboat stations]], the earliest of which, [[Fishguard Lifeboat Station|at Fishguard]], was established in 1822; in 2015 a quarter of all [[Royal National Lifeboat Institution]] Welsh rescues took place off the Pembrokeshire coast.<ref name="MM27Jan2016"/>

Pembrokeshire's diverse range of geological features was a key factor in the establishment of the Pembrokeshire Coast National Park and a number of sites of special scientific interest (SSSIs).<ref name="PCNPAGeology"/> In the north of the county are the Preseli Mountains, a wide stretch of high [[moorland]] supporting sheep farming and some forestry, with many [[prehistoric]] sites and the probable source of the [[bluestone]]s used in the construction of the inner circle of [[Stonehenge]] in England.<ref name="DATPreseli"/> The highest point is [[Foel Cwmcerwyn]] at {{convert|1759|ft|m}}, which is also the highest point in Pembrokeshire. Elsewhere in the county most of the land (86 per cent according to [[CORINE]]) is used for farming, compared with 60 per cent for Wales as a whole.<ref name="BBCNews9Nov2017"/>
