Then you will come to a crossroads where on one side is the first buffala farm and on the other side you can go to the bird observatory of Vilaüt. Then pedalling through fields of crops, farms with horses and cows up to the square of Castelló d’Empúries, where I recommend a walk in medieval streets and visit its various cultural attractions.
