Mae Labyrinth y Brenin Arthurs yn atyniad i dwristiaid yng Nghanolfan Grefft Corris, sydd ychydig y tu allan i bentref Corris, Machynlleth. Mae’n ailddefnydd ffansïol o hen gloddfa lechi ac ogofâu – felly mae o dan y ddaear ac ymweliad het galed. Mae ymweld yn golygu teithio ar gwch a throed gyda thywyswyr.
King Arthurs Labyrinth is a tourist attraction in the Corris Craft Centre, this is just outside of the village of Corris, Machynlleth. It is a fanciful reuse of an old slate mine and cave complex – so it is underground and a hard hat visit. Visiting involves boat and foot travel with guides.
