Get on board with the versatile, fast-growing watersport of stand-up paddleboarding. Local paddling fanatics tout the sport for its motor-free serenity that puts them close to nature while providing a serious core workout. (An hour of paddling burns up to 1,000 calories.) Picture surfing Minnesota-style: no waves and a seemingly endless terrain of calm, flat water. Rent paddleboards by the hour at Lake Calhoun and Lebanon Hills Regional Park. On your way to the cabin? Local retailers like the Scuba Center rent and sell them.
