We'll be driving to San Sebastian from the Costa Brava and staying in the SS area for 4-5 days in late August. We'd like to stay in SS but also visit Bilbao, Hondarribia, and San Juan de Gaztelugatxe (assuming this will be reopened by then -- are the chances good?).
Is it convenient to have a car for our explorations, or are we better off just returning it and using bus/train to get to nearby sights? (Or we could visit the areas where a car is helpful in our first couple days and then return the car after that...) If we are without car, is there a particularly convenient area to stay in SS? We were going to try to get something by La Concha.
We'll head down to Madrid by bus or train afterwards.
