Reserve your Torre Tavira slot before locking in day one
Torre Tavira (173 steps up to the camera obscura, €8 general entry) can only be visited by prior appointment booked through its official website. Because each guided optical session lasts 45 minutes and last admission is one hour before closing (18:00 from October to April, 20:00 from May to September), book your slot first and build the rest of your Old Town walk around it.
