Yes. Since Peñafiel sits in the middle of Ribera del Duero, many travelers pair a visit to the castle and plaza with a stop for wine tasting at a local bodega, enjoyed responsibly as part of the day. You can also combine it with nearby towns along the Duero if you'd rather see more of the region. Because the itinerary is built around your private vehicle, you can shape the stops around what interests you most instead of sticking to a fixed tour route.
Peñafiel sits about 183 km (114 miles) from Madrid, 60 km (37 miles) from Valladolid, and 108 km (67 miles) from Burgos. A private transfer typically takes roughly 2 to 2.5 hours from Madrid, 45 minutes to an hour from Valladolid, and around 1.5 hours from Burgos, door to door with no transfers. Public buses and trains can reach the wider area but usually involve longer travel times or a connection through Valladolid, since Peñafiel isn't on a direct rail line from Madrid.
Most travelers need around 3 to 4 hours to see the castle, its wine museum, and Plaza del Coso at a relaxed pace, including time to walk the old town streets below the fortress. If you want to add a wine tasting or a stop in a nearby town, plan for extra time on top of that. A private itinerary lets you decide how long to linger at each spot rather than following a fixed group schedule.
Rather than the usual rectangular arrangement, Plaza del Coso is an oval, bullring-shaped square lined with wooden balconies that once served as private viewing boxes. It's still used today for traditional bullfighting events and local festivals, making it one of the more distinctive surviving examples of this style of medieval square in Spain. Walking through it feels different from any plaza you'd find in a major city.
The castle's unusual elongated silhouette, often compared to a ship's hull, is visible from miles around and offers sweeping views over the Duero valley and surrounding vineyards. Inside, it houses the Museo Provincial del Vino, which traces the history and craft of winemaking in Ribera del Duero through exhibits on grape growing, barrel aging, and regional traditions. It's a natural way to understand the wine region before or after tasting it firsthand.
Peñafiel packs an outsized punch for its size. A dramatic 100-meter-long hilltop castle shaped like a ship dominates the skyline, the medieval Plaza del Coso is one of Spain's most unusual town squares, and the whole area sits at the heart of Ribera del Duero, one of Spain's top wine regions. It's an easy add-on if you want history, architecture, and wine country in a single outing rather than a full day of city sightseeing.
