Mar Menor 
The paths of the Mar Menor and Calblanque Spaces are located within four Protected Natural Areas.
These are the Regional Park of Salinas de San Pedro, Regional Park of Calblanque, Protected Landscape of Cabezo Gordo, and Protected Landscape of Open Spaces and Islands of the Mar Menor.
Access to these natural spaces is possible from the Mediterranean Motorway AP-7 (Salinas de San Pedro and Carmolí), La Manga Fast Lane MU-312 (Calblanque), and C-3319 (Cabezo Gordo).
The Network of Natural Trails of the Region of Murcia traverses areas of great natural value, we must respect and preserve them for future generations.
EQUIPMENT: Hikers must have appropriate footwear and clothing according to the season of the year.
WEATHER: Make sure you check the State Meteorological Agency information (www.aemet.es), carry plenty of water, a hat, sunscreen, and sunglasses, specially during the summer as there is high insolation and temperatures in the Region of Murcia.
ORIENTATION: Trail information and signage do not guarantee the absence of orientation problems. Carrying a map of the area, a compass, and/or GPS is advisable. Maintaining signs and infrastructure is crucial for everyone’s safety and enjoyment. Report any deterioration or loss to the forest ranger, personnel of the Natural Spaces, or the Directorate General of the Natural Environment.
It is important to assess the route’s duration and difficulty according to our physical capacity and experience. The difficulty levels (M.I.D.E. System) are designed for optimal seasons and favorable weather conditions.
The risk on the trails is low, but it is not absent and its route’s duration is calculated as the effective walking time, excluding breaks and stops.
It is the hiker’s responsibility to keep the trails clean and dispose of any garbage in nearby containers.
Fires should only be lit in designated places and times.
Forest fires are a serious threat to natural spaces.
Plants should not be collected, nor should wildlife be disturbed.
Binoculars and a camera are useful for enjoying and documenting nature.
Staying on the proposed trail limits and respecting private property and local ways of life is essential.
If trails pass through roads suitable for motor vehicles, walk on the left side and, if in a group, in single file. In an emergency, call 112.

Next to the roundabout dedicated to the flamingo, an emblematic image of the Park, you will start towards the Pinar del Coterillo, surrounded by the captivating landscape of the salt pans.
Once at Curva de la Culebra, join the Senda de El Coterillo (local trail with white and green markings) to head south, parallel to the road, towards the Coterillo Information Point.
Before that, visit the bird observatory of the Charca del Coterillo, the only wetland not used for salt production. On the right, observe the Salinera Central, the nerve center of traditional salt resource use.
From the recreational area of El Coterillo and next to the Marine Resources Center, cross the road towards Llana Beach. Parallel to the San Pedro Port parking lot, arrive at the beach’s beginning next to the Red Cross lifeguard station.
From here, a long and pleasant journey begins, taking us along Llana beaches to Punta de Algas. The name “algas” (algae) is due to the amount of oceanic seagrass sedimented on its shores.
Before Punta de Algas, cross the dunes to head west on firmer ground, again accompanied by the salt pans. On the left, distinguish the traditional fishing use of the Encañizadas. This capture art takes advantage of the natural corridor between the Mar Menor and the Mediterranean Sea to trap fish in their seasonal movements.
Our steps will turn north, between the waters of the Mar Menor and the salt pans, to reach one of the iconic elements of the Park, the Molino de la Calcetera. Together with the subsequent Molino de Quintín, it was used for emptying and filling the salt pans.
Shortly before finishing the long straight stretch, discover the popular Mud Baths, attributed therapeutic and healing properties. Close the complete return to our trail by walking along the urban promenade, which, along the Park boundary, leads us back to the roundabout where you started.
