River's Edge Kayak & Canoe Trips' owner Lollie Mercer likes to joke about being in the business of curing nature-deficiency disorder. It's certainly true that sunlight and exercise provide the body with a whole host of benefits, and Lollie's customers get plenty of those riding the rapids of the Russian River. She and her staff outfit guests with one of six types of boats, which include styles that range from the classic canoe to double kayaks. Self-guided groups embark on three- to six-hour trips where they navigate Class I and II rapids. When the water calms, they can view the abundant wildlife along the river's banks, including osprey, eagles, otters, and turtles. Eventually, groups land at River's Edge Beach, where Lollie and her crew collect gear and guests reunite with their less-awesome land-based vehicles.
