Dolgellau to Machynlleth via Tywyn or the Centre for Alternative Technology

With two route options that combined make a great circular ride, these sections of Lon Las Cymru take you through the heart of Snowdonia, and along some of the amazing Welsh coastline.
Taking the coastal route option, you traverse the coastal hills with stunning views north and out to sea, before dropping to Tywyn, home of the Talallyn Railway, and then going out to traverse the hills once a gain to Machynlleth.
The inland route is more direct but includes a pass that climbs to over 400m above sea level, before descending to the old slate mining villages of Aberllefenni and Corris. The route also passes the world renowned Centre for Alternative Technology.
If you are particularly adventurous, why not turn both route options into one large circular.
