Algarve Coastal Drive

Ninety kilometres of sandstone cliffs, sea caves, and hidden grottos separate Lagos from Faro on Portugal’s Algarve coast. The A22 motorway crosses the same distance on an electronic toll with no barriers, but the free N125 stays closer to the water and takes about two days to enjoy properly, with fuel running near EUR 12 round trip.

Practical Tips

• Take the N125 and M-roads, not the A22 motorway — the coast is invisible from the inland highway
• The A22 uses electronic tolls (Via Verde) with no toll barriers — rent a car with a toll transponder, or foreign-plated cars can pay after the trip through pttolls.com
• Benagil Cave is only accessible by water — rent a kayak in Benagil village (EUR 20, 1 hour)
• Park at clifftop viewpoints and walk down to beaches — cliff-edge paths are often more scenic than the drive
• The Algarve has 300+ sunny days per year — sunscreen is essential even in October
