Snoswhoeing around frozen Spooner Lake in Nevada was a very scenic and fairly easy trek. Spooner Lake is located a little inland from the eastern shore of Lake Tahoe.
Eagle Falls is a scenic set of subalpine waterfalls from Eagle Creek which flows from Eagle Lake above. Probably best in summer but you can go anytime. Be sure to check out the upper and lower sets to take in all the views.
A great snowshoe trip trailblazing the Rubicon Trail in Emerald Bay down to Vikingsholm, through the Eagle Point Campground. A highly recommended snowshoe trip while in South Lake Tahoe.
