We are planning a three-day trip down the coast in August from Barcelona to Zahara de los Atunes, just northwest of Tarifa, where we have booked an Airbnb to watch the total solar eclipse. What are the top coastal towns to visit? I have a suggestion of Altea, Nerja, Peniscola, Sitges, and Conil de la Frontera. What do you think? (We know that three days is not enough time to visit them all.)
Also, what are the rail connections like between those towns? Barcelona to Sitges seems straightforward, but I'm not sure about the others.
