The marvelous tones of nature provide a splendid backdrop for this route, where the region’s magnificent historical heritage is also one of the highlights. This is a fascinating route that begins on the bank of the River Guadiana in Vila Real de Santo António and takes you to Castro Marim, where you will certainly be impressed by the magnificent castle, one of the most important medieval monuments in Portugal. The road up to the Monte Rei golf course is good and traffic is usually light. Along the way you will pass by Curral de Boeiros before starting the descent to the Asseca Valley, always surrounded by the eastern Algarve’s beautiful scenery. A final uphill stretch now, to reach the village of Santo Estevão, and the route is complete, but along the way you will undoubtedly want to pause for a moment and enjoy the view over the Ria Formosa in the fishing village of Santa Luzia.
