Aveiro is a perfect stop to rest between the cascading waters of Gerês and Coimbra. Nestled along Portugal's northern coast, it is often called the "Venice of Portugal" for its enchanting canals and the colorful gondolas that glide through them. Here, you can not only drift along these serene waters, but also admire the striking striped houses that line the streets, taste the famous Ovos Moles — a sweet, delicate treat — and even catch the waves at Aveiro's coastline.
