The Mar Menor

Highlight • Lake

Top location, not just as a place to swim, there are beautiful views here. Just take a short stop and take in the wonderful perspectives.

The Mar Menor, Spanish for "Little Sea", is actually a saltwater lagoon. The "Little Sea", known for its warm and shallow water, is a popular destination for tourists and locals alike and offers a variety of beaches along its coast. A very beautiful and worthwhile destination for a bike tour.

Los Alcázares Town Entrance

Highlight • Settlement

We are in the Murcian municipality of Los Alcázares, located on the banks of the Mar Menor, with beautiful beaches, natural landscapes such as the Marina del Carmolí or great gastronomy, the most typical dish being the cauldron, cooked with fish and rice.

Portman Climb via Cola del Caballo

Highlight (Segment) • Climb

Portman is one of the areas most frequented by cyclists in the Mar Menor area. This climb begins when leaving the town in the direction of La Unión, where we immediately find a very sharp and steep right-hand curve (right here is the parking area to go down to the Cola del Caballo cove). The ascent is about 2.5 kms at 5.7% with a peak above 10%.

Portmán Bay Roundabout

Highlight • Structure

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...
