INTRODUCTION
View of north Gower from the ascent of Cil Ifor Top (Walk 30)
The Gower packs a glittering array of features into a remarkably compact and unspoilt area. Justifiably selected in 1956 as the UK’s first Area of Outstanding Natural Beauty, this tiny South Wales peninsula boasts some of the most scenic beaches anywhere in the world, alongside fascinating geological formations, ancient archaeological sites and striking buildings from its more recent history.
An added bonus for holidaymakers wanting to stretch their legs is the number of rich and varied walks that can be found in an area just 25km long by 13km wide, with spectacular landscapes easily accessible in all directions. The land oozes with interesting wildlife, landscape and cultural features, and each walk described in this guidebook endeavours to capture this diversity and richness. A haven for walkers, photographers and nature lovers, Gower draws visitors back time and time again.
The peninsula is known for its spectacularly steep, rugged coastline and picture-perfect golden sandy beaches. But there is much more to the Gower and the 30 circular routes described here will take readers into the little-explored valleys, hills and ridges found inland. Many of the routes combine a section of coastal path, which may visit a secluded cove or wide-sweeping beach, with a ridge offering stunning panoramic views or with a tranquil stream valley. All avoid road-walking wherever possible.
Some coastal areas are well frequented, such as those around Langland, Oxwich and Port Eynon, but this guidebook focuses in the main on the lesser known parts where you will really be able to escape the crowds and find peace and solitude.
Geology
The continental plate on which Gower has formed was once situated south of the equator and has been drifting northwards over the past 425 million years. As a result, the sedimentary rocks that now comprise Gower were deposited under widely varying climatic conditions, from tropical seas rich in corals to coastal swamps.
The oldest rocks cropping out on Gower are from the end of the Devonian period and they form the cores of the major anticlines. During this period Gower lay in a region where sediment-laden rivers crossed a wide plain between mountains to the north and the sea to the south. The mountains were made of still older rocks whose roots now form much of central and north Wales. The climate at this time was tropical, possibly monsoonal, and the streams carried away coarse sediment from the intense erosion in the hills and deposited it across the braided river channels. In Gower we see pebbly rocks – conglomerates – at the top of the Devonian sequence overlying coarse sandstones, and these form the high ground of Cefn Bryn, Llanmadoc Hill and Rhossili Down.

The Devonian period ended approximately 360 million years ago when changing sea levels caused the sea to advance northwards. Initially mainly muddy marine sediments were laid down over the continental conglomerates, becoming dark, fine-grained shales, but gradually the amount of river-borne detritus diminished to leave clearer waters.
In these equatorial warm, clear waters calcium carbonate precipitated in the form of shells and skeletons from the abundant corals, shellfish, brachiopods and crinoids (sea-lilies). This became the Carboniferous limestone series that comprises grey calcareous shales and massive limestones. The rocks are divisible into three groups: Lower Limestone Shales, Main Limestone and Upper Limestone Shales; however, there are many different rock types within these groups, each with varying textures, thicknesses and fossils as a result of subtle environmental changes. Overall it is about 800 metres thick, but becomes progressively thinner to the north, where the sea was shallower and more susceptible to interruptions of sedimentation as sea levels fluctuated, leading to the absence of some layers.

These stable conditions were interrupted around 320 million years ago by earth movements caused by approaching continents from the west and south. The compressive forces within the earth’s crust caused the nearby landmass to be forced upwards and the increased rate of erosion flooded the limestone sea with sediments of sand, shale and mud from the river deltas.
This transition from limestone is marked by a coarse sandstone known as millstone grit, originally laid down by fast-flowing rivers. In its lower layers the gritstone contains massive white quartz conglomerates and sandstones, within which there are very pure bands of over 99 per cent quartz that were once worked for firebrick.
The next succession, the Coal Measures, originated in a widespread system of river deltas close to sea level, upon which grew lush tropical forests of giant mosses, horsetails and ferns that eventually became the coal. The Measures consist of sandstones, shales and coals arranged in a repeated sequence, as the forests flourished
