Worth climb to the cairn for the downhill section on the main access road. Then drop into single track round the back lanes of Carharrack. Sweet! :)

Portreath is a a small coastal village with a very narrow harbour and sandy beach. Rather than fish, this port was used to import Welsh coal and export copper. The original loading ramp can still be seen and given the narrowness of the harbour, navigating it must have been very difficult and dangerous. There are several cafes and shops in Portreath if you are in need of refuelling and/or rehydrating.

The 7.3 km long circular route takes you back to a time when Cornwall was covered by sea and then became a Europe-wide mountain range. The sedimentary rocks of this area around Portreath were deposited in a deep marine environment during the Devonian age (ca. 393 - 373 million years): Greywacken: Gray rock with fine to coarse grains (0.3 - 2 mm; 0.01 - 0.08 inch), consisting of quartz, feldspars and fragments of foreign rocks. In some cases, shiny/shimmering components can be seen (mica), the rocks form layers and banks. Siltstones: Light gray rock with fine grains (<0.063 mm; <0.002 inch) that are not visible to the naked eye. Layers can be recognized based on the color difference. Slate: Gray to black, sometimes slightly red to greenish colored rocks with very fine grains (<0.02 mm, <0.001 inch), the rocks appear foliated with very thin layers, often alternating with greywackes. The originally horizontal sedimentary layers of Cornwall were tectonically overprinted around 323 - 299 million years ago during the Variscan orogeny (mountain formation). During this time, the southern major continent Gondwana collided with the northern major continents Laurentia and Baltica as well as smaller continent fragments (terranes) such as Avalonia and Amorica. The orogeny ended approximately 270 million years ago with the formation of the supercontinent Pangea. Due to the pressure from the south, the sedimentary rocks were compressed, folded and internally transformed under increasing temperatures. This is how slates emerged from the original claystones. There are no deposits in the area for the period between the formation of the Devonian rocks until 3 million years ago. During the Ice Age 3 million years ago, the region of modern-day Cornwall lay in a tundra area south of the glaciers that covered the Northern Hemisphere. Periglacial deposits from this period can be observed on the cliffs.

To the west of this bay, a rock wall protrudes into the bay and divides it. This wall is the result of long-term erosion, which led to the collapse of a former cave. The name Ralph’s Cupboard comes from a legend that the giant Ralph lived in this bay. This giant attacked the incoming ships and stored the recovered treasures in the cave, his closet. The eastern side of the bay shows a typical cliff with dark gray shales and greywackes at the lower end and periglacial deposits at the upper part of the cliff.
