landscape in the Rhinogydd and the fame of Snowdon as the highest peak in Wales. The Rhinog mountains are popular with hillwalkers looking for a more isolated, wilder walking experience. The peaks of the range are most easily accessed from the west side. Two valleys - Cwm Nantcol ('valley of the Nantcol (stream)') and Cwm Bychan ('small valley') - lead deep into the mountains and may be reached from the village of Llanbedr. The most popular walking route in this area begins at the Roman Steps at , which leads from Cwm Bychan through Bwlch Tyddiad and around Rhinog Fawr. Despite the name, these steps are not Roman and are in fact the well preserved remains of a medieval packhorse trail leading from Chester to Harlech Castle. At the top of the Roman Steps, the route curves around the eastern end of Rhinog Fawr and enters Cwm Nantcol via Bwlch Drws Ardudwy ('pass of the doorway of Ardudwy'). A different path leads from Cwm Nantcol, passing around the western end of Rhinog Fawr back to Cwm Bychan via Gloywlyn ('gleaming lake'), completing a circular route that can easily be completed in a day.
