I began my
Camino Frances in SJdPP on April 30th of this year and finished in Santiago de Compostela on June 5th. I chose that time of year specifically because I hoped to take advantage of the Springtime floral display, and I was not disappointed! The Flanders poppies always brought a smile to my face, as did the yellow fields of rapeseed, aka mustard. Occasionally, I even saw some California native plants, such as Western Redbud. I was so glad I went when everything was green and in bloom! As for the fauna, I didn't see a whole lot of wildlife - a snake here, a few lizards there. However, I will take exception to Tinkatinker's comment above. There were days on the Meseta when I was swatting at flies all day long! Drove me out of my mind! The black and white birds mentioned above are magpies, and they're everywhere. And the vultures over and around the Pyrenees were amazing! Of course, all the usual domestic animals - cows, horses, sheep, dogs and cats. I don't have any other time of year to compare to, as that was my first and only Camino (so far), but from my experience the timing of your journey is just perfect!
