I've ridden both sides several times and thoroughly enjoyed it. Ideal for gentle climbing and beautiful scenery. Highly recommended.

According to Parliamentary Question E-2325/2003 to the European Parliament, millions of tons of waste were dumped in Portman Bay between 1959 and 1989. It is estimated that approximately 13 million cubic meters of mud are flooding this bay, causing the 1957 shoreline to shift approximately 300 meters inland. This waste contains sulfides, arsenic, cadmium, copper, mercury, lead, and zinc, as the experts consulted acknowledge. One of Europe's greatest environmental disasters, so it's not a "highlight," but it's still a beautiful cycling route...
