Pristine Bear Lake on the Utah/Idaho border is only 125 miles from Salt Lake City.  It is a vacation wonderland for sailing, fishing, camping and water skiing.  Only 15 miles away is Beaver Mountain Ski Area that challenges even expert skiers.  Snowmobile from Bear Lake to Hardware Ranch on groomed trails.  The water changes color by the minute from cobalt blue to deep blue to turquoise to ice blue to emerald green depending on how the light shines on it.  
It will take your breath away!
