The huge, black church at Arucas however, opens its door every day between 09.30 and 12.30 and again for an hour or so at 18.30 for evening mass. It's worth timing your visit to Arucas to coincide with opening time because the interior of the church is as impressive as its Gothic exterior.
Alex says: The Arucas church wasn't always black. The original basalt stone was a blue-grey colour but has darkened over time.
Opening hours for the Arehucas rum factory are similar: Weekdays 0.900 to 14.00 (13.00 between June and September). No visits at the weekends.
