The road from La Güira to the Cuevas de los Portales is about 15 kilometers. It looks like it goes through the highest mountains, and is said to be very scenic. However, locals said that it's impassable by car. It might be a good hike or mountain bike ride.
A better, but longer, way to drive to the Cuevas de los Portales is on the highway from Entronque de Herradura to La Palma, about 20 kilometers.
