I will be on a cruise chip that docks at the San Antonio terminal in Chile. I want to find the best way to get to Neruda's house La Sebastiana in Valparaiso (hopefully public transportation). I think it is a little over an hour away.
Sherry - There is a day tour company that would lessen the burden on you transportation wise and provide a convenient way to tour Neruda's house La Sebastian.
Using public Transport: Take bus from San Antonio Terminal to Santiago
From Santiago Pajaritos bus terminal in Santiago, take a bus to Vailpraiso
Neruda's oceanside home, Isla Negra, is closer, if you find getting to Valparaiso a challenge. We stopped there as part of a tour, so I couldn't tell you how to get there, but it was a museum in itself. It has a beautiful setting right on the ocean, and Neruda and Mathilde are buried there.
