Yes! The 'official' itinerary adds another 12 km to the route and ends in Grado. From there, you can either take a bus or train back to Oviedo, or stay for one or more nights (perhaps even in one of the pilgrim albergues) to visit Grado and surroundings. If you are thinking about extending the tour, we have another tour for you that provides you with all the information that you need to walk the second part of the trip on your own (see our 8-hour activity 'A Taste of the Camino de Santiago').
