It appears that there are several wonderful nearby areas to visit from Bilbao (aside from the Guggenheim and pintxo places) that can be reached by public transport. I figure about two days for Bilboa proper.
We will have a car and will be coming from Donostia environs (after 5 days) and heading to Burgos and beyond after Bilbao. Are there other day trips we should consider to which we could drive (within an hour)? [Note: Our interests lie in scenery (easy walk/hikes of a mile or two), charm, architecture, history.] If so, where might be a good location for hotel/short-stay places/etc. that might give us access to Bilbao's public transport as well as easy access to driving routes? How many days should we allocate to this housing location?
Any tips will be very much appreciated!
[We hope to cover Bermeo, Mundaka, Guernika, Gaztelugatxeko from Donostia. As Mikel has previously suggested, places reachable by public transport could include (copied and pasted from his posts): "Line 1, stop at Areeta for the amazing Puente Bizkaia, a unique UNESCO World Heritage Monument (I live a mile off it), in Getxo (not Bilbao, a town in the outskirts). Next stop, Algorta, for the quaint old fishing port and its narrow cobblestone streets. You may want to continue to Plentzia, a "hidden" coastal town very frequently ignored by tourism (but we locals love it!!), beautiful port, beaches and old quarter. Also, in Bidezabal stop, you may want to continue to the cliffs of Punta Galea, great views of the estuary of the river of Bilbao. Santurtzi lost a lot of appeal in the 60s, with the industrialization, I would visit no doubt Portugalete instead (in fact, I would use the Puente Bizkaia to cross from one side to the other)."]
