1. Waterfront Trail, Whitby
The hard part will be deciding where to go: The Waterfront Trail stretches for more than 3,000 kilometres along Lake Ontario, Lake Erie, Lake St. Clair and the Niagara, Detroit and St. Lawrence rivers. It connects 140 communities with hundreds of parks and natural areas, including wetlands, forests and beaches. One family-friendly choice is a 3.5-kilometre (one way) paved stretch that starts at Rotary Sunrise Park?kids will love the long pier out onto Lake Ontario. From there, head east to Kiwanis Heydenshore Park. Spend time enjoying the playground and outdoor gym equipment by the lake, and then move on to the forest trails of Thickson?s Woods Nature Reserve, home of the last old-growth white pines on the north shores of Lake Ontario.

2. Twin Bridges Trail, Massey
Waterfalls are a wonder to look at, and this six-kilometre round-trip hike along the shores of the Aux Sables River starts at Chutes Provincial Park?s main waterfall and continues past the Seven Sisters cataracts (a series of smaller waterfalls). Rated as easy, the trail is wide and groomed, with a number of lookout platforms and benches. Tip: Save this one for fall, when the brilliant changing leaves are reflected in the water.
