50 km - 1/2 hour
Leave Huelva City centre to the west and cross the new bridge over the River Odiel. After 6km turn left on the H414. 9km on you will join the main N431.
If you have time take the coast road. The beaches ere are some of the best examples of expansive golden sands backed by sand dunes. Punta Umbria is a well kept coastal resort at the mouth of the River Odiel. El Rompido further west overlooks an interesting sand spit.
Lepe is the first town you meet. It does have a few interesting features but is normally by passed by tourists.
Ayamonte is the Spanish border town. The car ferry to Portugal, which served travellers for many years before the bridge, still runs from here. If you have the time use it to cross the River Guadiana to San Antonio in Portugal.
The N431 continues west and you will cross over the River Guadiana on the modern suspension bridge. Hardly noticing customs formalities you will now be in Portugal.
