While in Santiago, my boyfriend and I plan to take a side trip to Melipilla and Pomaire. Rather than return to Santiago, we are hoping to go to Valparaiso and spend the night for a later return to Santiago. We have the info on Santiago to Melipilla by bus and then collectivo or taxi to Pomaire. What are options from Pomaire/Melipilla area to Valparaiso? We have some basic Spanish, and like travelling in the local fashion. We can splurge a bit economically if we need to. Gracias.
