This route starts and finishes in Los Belones and will take you to the bay of Portmán, one of the most gorgeous and lonely places of the coast, and the famous La Unión mining area.

Length: 24 kilometres. Maximum unevenness: 240 metres.
Difficulty: easy. The only difficult parts are two little saddle points you have to go through, first to enter Portmán bay (100 metres) and then to cross the mining mountain range (240 metres).
Duration: three hours.
Recommendations: try not to go during the hottest hours and walk carefully along the tarmacked areas. In the mining mountain range do not get close to the wells.

Interesting places:
- Portmán. The Roman Portus Magnus has suffered the worst ecological attack in the entire Mediterranean coast. The waste dumping from the mining areas has covered this beautiful bay and turned what used to be a flourishing fishermen's village into a small interior village. The landscapes and cliffs around this area are incomparable to anything else on the Mediterranean coast. From here, the ships from Imperial Rome extracted tons of iron and other minerals that travelled on triremes to all corners of the empire.
