It was a solo trip and tour for me, and Angel still puts in a ton of effort to make it fabulous. He is very knowledgeable about the region, the town, the modern history, the people, and of course the geological aspects of Zumaia. If you do not know the difference between a sedimentary and a metamorphic rock, don’t worry! There is some vague memory of those terms from some science class years and years ago, so in my ignorance, Angel was very patient about summarizing the basics and teaching accordingly. Anyhow, the tour really helped put my trip into the Basque Region into some sort of context, and it was an excellent supplement to the Museo San Telmo. The views and the scenery were much better than I would have ever seen on my own. The walk in and out of the city was moderate; although there was a big hill to climb, the walk up to the whale watching spot was very gradual and pleasant. As I was there on a rainy/stormy day, Angel was careful with the weather and the poncho he provided definitely came in handy! The pintxo at the end of the tour was the best I tried during my time in the Basque Region. Oh, and Angel brought along his camera (high quality) and took pictures along the way. He sent them to me the following day, and that was a very nice touch. If you are concerned about getting to Zumaia from San Sebastián, I understand! I was a little apprehensive about trekking that way without a rental car, but it was actually fairly easy. Angel recommended that I take the 13:50 Euskotren train from San Sebastián (Amara Donostia) for the 3pm hike. I believe it takes 38 minutes to get from Amara Donostia to Zumaia. Once you arrive at the station, you will walk about 0.5 miles to the meeting place. I just bought a ticket at the station kiosk before each trip (2.55 Euros).
