We've been wilderness camping on Lake Richardson with South Arm Campground for many, many years.  Wilderness camping isn't for the faint of heart, but it's a way of stepping out of the fray and reconnecting with nature.  Campground staff are kind, helpful and accommodating.   Swimming is a top notch, as is kayaking, and canoeing.  The lake is a bit boney, so take care to mind the rocks, if you are motor boating. The loon calls are like nothing I've heard anywhere else.  What an amazing experience and place to recharge!
