The air temperature was a pleasant 28°C. A few showers caused some cooling, but the sunny days more than made up for it. Wonderful climate.
Silke MustafaAlthough there could be the occasional thunderstorm, I greatly appreciated the bright, sunny days and fresh mountain air. The cool nights provided a welcome contrast. Good for nature lovers the world over.
LaraThe sunny days were idyllic, but the sudden transition to very cold nights was unpleasant. The snow added to the charming aesthetic, but made travel difficult.
