Take the bus
Visitors can tour the wineries of Rioja Alavesa while leaving the driving to someone else.
Enobus is a motorcoach that runs three routes stopping at several Basque Country towns with wineries. Riders can request audio guides in English, Spanish, Basque or French. The buses run seasonally (mostly on weekends) from March through June and October until early January. Round-trip tickets cost 10 euros (about $13) for adults with half-price rates for children and seniors.
Reservations can be made over e-mail by writing to enobus@arriagabus.com or by calling 011-34-945-285-000 from the United States. If you're calling within Spain, no need to dial the 011-34 portion of the phone number.
