Crymlyn Bog National Nature Reserve, near Swansea
The largest lowland fen in Wales
A stunning landscape ranging from dramatic cliffs to headlands and from woods to dunes on Pembrokeshire’s south coast
Stackpole National Nature Reserve is in south Pembrokeshire and is one of the most breathtaking locations in Wales.
The reserve’s diverse landscape includes the shallow freshwater Bosherton lakes, woodlands, dunes, limestone cliffs and beaches.
Few places around the UK contain such a variety of habitats and wildlife in such a relatively small area.
The cliffs demonstrate the geology of Stackpole.
They are topped by a limestone plateau which was lifted from the sea-bed around 50 million years ago. Look closely and you will see a band of lighter rock, the compressed remnant of an ancient beach, formed when the sea level was much higher.
Two of Pembrokeshire’s finest beaches – the sheltered havens of Broadhaven and Barafundle Bay –lie within the reserve.
Stackpole is an area of limestone grassland and ancient dune grassland which was created during the fifth and sixth centuries. It is bordered by scrub and woodland and, in the Spring, the area is alive with bird song and rich with flowers and butterflies.
Bosherston Lakes were created in valleys in the limestone in the 18th and 19th centuries by the Campbells of Cawdor, owners of the Stackpole Estate until 1976.
The calm surface of the lakes is adorned with white water lilies in summer, together with beds of bright green stonewort: these are a speciality of the lime-rich spring-fed crystal clear waters here.
Stackpole is a stronghold for several species, including one of Britain’s largest populations of the rare greater horseshoes bats.
The lakes are abundant with wildlife especially otters, water birds and dragonflies.
The limestone cliffs, dunes and maritime grassland support many kinds of special plants and animals, including diminutive soil and rock lichens, numerous flowering plants, scarce insects and breeding populations of chough and colonial seabirds.
The National Trust owns and manages the reserve in partnership with Natural Resources Wales.
The Trust operates four car parks at Stackpole (Stackpole Quay, Broadhaven Beach, Bosherston Village and Lodge Park) and a tea room at Stackpole Quay.
Within the Trust’s estate at Stackpole, there is an extensive network of footpaths, some 10 kilometres of which are in the reserve. There are also eight miles of cliff-tops and magical beaches on the Stackpole Estate.
Information about the reserve and the Stackpole Estate is available at the car parks and tea room during the summer months.
The Stackpole for Outdoor Learning base camp and the adjacent Stackpole Centre welcome organised parties of visitors and educational visits by prior arrangement.
Please check the National Trust website for further information about visitor facilities.

Read on to find out what you could see here during the different seasons.
As the days lengthen, the woodlands come alive with early purple orchids, primroses and pungent wild garlic.
In the grasslands and sand dunes, there is a colourful display of spring squill and cowslips. Thrift comes into flower on the cliffs and the edges of the lakes turn yellow with marsh marigold.
The cliffs are home to many seabirds such as choughs, guillemots, razorbills and even a few puffins.
You may also spot bats in the woodlands at twilight or feeding on insects over the lakes.
The woodlands are home to the silver washed fritillary butterfly while other butterflies such as the dark green fritillary, common blue and brown argus may be spotted on the grasslands and sand dunes.
Summer brings a varied display of wild flowers to the reserve. Bee orchids, common spotted orchids and wild thyme appear in the grasslands and on the sand dunes and white water lilies grace the lakes. Thrift is still in flower on the cliffs and is joined by golden samphire and wild thyme.
Skylarks can be heard singing overhead and reed warblers can be spotted in the lakes.
Just as in spring, the cliffs are alive with seabirds from choughs to guillemots and razorbills to puffins.
As the weather turns cooler, the grassland is dotted with colourful waxcap fungi and the spindle trees are covered in their distinctive pink fruit.
There’s plenty to see at Stackpole in the winter.
Over the grassland, the hobby (a small falcon) is busy hunting for small birds.
Surrounded by the stark colours of dogwood at the water’s edge, the lakes are a good place to spot a wide range of wintering and other birds including:
