Water World: Ways to Cool Down in the Capital When the summer sun is out in full force and temperatures soar, sometimes you need more than air conditioning to cool you down. Fortunately, Ottawa is replete with fun ways to chill out. From beaches to rafting to waterslides, here are some of the best ways to get wet in the capital. Mooney's Bay during HOPE Volleyball Summerfest LIFE'S A BEACH We may not be a coastal city, but that doesn't mean we don't have beaches. A plethora of lakes and the seemingly unending coastline of our rivers provide Ottawans with many a swimming hole. Mooney's Bay on the east shore of the Rideau River is one of the most popular. Its sandy shores and rows of beach volleyball courts draw throngs of sun seekers all summer. It's even the site of the largest one-day recreational volleyball event in the world -- the HOPE Volleyball Summerfest. Britannia Beach on the Ottawa River in the city's west end is another gem. Its close proximity to the Britannia Yacht Club makes it great for both swimming and boat-watching. Lake-filled Gatineau Park also offers plenty of swimming beaches. O'Brien and Blanchet Beaches on Meech Lake, Breton and Parent Beaches at Lac Philippe, and La Pche Beach at La Pche Lake are all open to the public and staffed with lifeguards during the summer.
