We stayed in a seaside palace, which in itself is imbedded in memory. Exploring this tiny town on the Spanish border was a daily excursion not to be missed. The people were friendly and very helpful. Food hunting/finding was a major part of the first couple days and all our purchases were delectable!
Biarritz is a surfing "hot spot" and, while not necessarily the greatest place to swim, the beach is crowded on weekends and the Atlantic is wonderfully refreshing on a hot afternoon. People, young and old, from the Basque area (French and Spanish) gather on the (tops optional) free beaches for fun and relaxation.
As for the remainder of the community, I'll have to do home research but, basically, we just explored the town on our own as it was terribly hot and I was reluctant to venture into Spain because of the heat and the beneficial sea breezes (at the hotel) -- all quite different from snowy New England, I assure you.
Quick Tips:
Most importantly, don't even THINK of actually swimming in the ocean there! The waves simply won't let you. Of course I learned that by experience and had quite the buffetting and when I took off my suit, it sounded like I'd broken a string of pearls as all the rocks came tumbling onto the bathroom floor!
Major suggestion: try to greet the natives in their own language and they'll respect (or -- as in my case -- laugh at) the effort. They were awesome to us with our every query: one young man gave us a foot escort to the post office since it wasn't really out of his way, and another gentleman stopped tending his garden to talk and give us directions, after which I thanked him and wished him "au jourdoui" and my daughter asked me (since I was talking at a fairly good pace) if I knew what I had just said to the man - oops! - meant "au revoir"! Sometimes a tourist there isn't red just from the sun.
Best Way To Get Around:
Mid-week, Biarritz is a quiet, almost sleepy town. The parts of our neighborhood that we experienced certainly had access to taxis (which is how we arrived at 3am), and the TGV rail station is in neighboring Bayonne, but we traveled within the town by foot exclusively. Bicycles seemed more prevalent than moving cars (which were parked on both sides of the streets), but still not plentiful. Also, we were lugging about 60 lbs. of school books and had lessons to do everyday, so we really never ventured even as far as the museum at Bayonne as I had originally hoped. But with each day being filled with bright sunshine and salt breezes, the roses all in full bloom, the heat of mid-day and being surrounded by so much to enjoy, we made plans on a minute-by-minute basis. We really just went with the flow and grew to know and love Biarritz our own way.
