En route to the village of Costa Brava, our group of students made its way over dirt ridges and hills, gazing at the vast, glittering ocean down below us. Closest to shore, the water was the shade of clear crystal and it grew darker as it reached the horizon, creating a beautiful contrast. There was a single white catamaran bobbing lazily in the distance. Surrounding the trail were lush trees, leafy bushes, and prickly cacti. Eventually, we reached an empty beach area and walked barefoot through the sand, letting our toes dance in the water.
