The picturesque “Lac Noir” is a tiny natural gem and a perfect spot for nature lovers. You can do plenty of activities throughout the year, and if courageous enough, even go for a refreshing swim. Located in Fribourg, at the border between the French and German Suisse regions, this mountain lake of only 0.5 square km, is a real attraction for families.
