Starting in the university town of Aberystwyth, Lon Teifi takes the same course as Lôn Cambria along the Ystwyth valley to Pont-rhyd-y-groes.
You'll then turn southwest to cross the watershed and drop down into the valley of the River Teifi which is followed all the way to the coast at Cardigan.
It passes through the handsome towns of Tregaron, Lampeter, Llandysul and Newcastle Emlyn (with its castle ruins).
There are several gentle valley sections, such as the approaches to Lampeter and Llandysul from the northwest but there are also many climbs where the route turns away from the valley floor.
The most noticeable climb of the whole route comes after leaving Cardigan and the Teifi valley as you head up into the hills then drop down to Newport.
Another noticeable climb follows the exit from Newport, but this is the last one as you descend into the Gwaum valley and reach journey’s end at the Ocean Lab in Fishguard.
