The unique color of the lake is caused by limestone particles suspended the lake. The particles reflect the rays of the sun and change the color to varying shades of blue. Bear Lake is estimated to be at least 28,000 years old. It is a large lake, reaching 20 miles from the northern border of Utah to the southern border of Idaho.

Bear Lake is a watersport paradise.
Each summer, the colorful sails of hobiecats are seen on the turquoise waters. Two major sailboat races are held during the summer. The east shore is popular for scuba diving in the summer and for ice fishing in the winter. A 45-mile loop around the lake is popular for cyclists. Watercraft rentals available.
