The best MTB trails around Ajax

Darren Park is a family-oriented park, with lots of activities for kids. In summer the splash pad is pretty popular, and there's a large playground, sandboxes, climbing structures, and even a themed play area with “dinosaur bones.” This park is the northern start point of the Whitby Hydro Corridor Trail.

Brick by Brick Park is a beautiful green space shaded by mature trees tucked along the city’s trail network. There are several outdoor fitness stations and plenty of open areas perfect for a picnic or simply a place to relax and connect with nature.

Following the Lake Ontario shoreline, the Whitby section of the Waterfront Trail offers long, easy walking and cycling routes with steady lake views, breezy open stretches, and access to several parks and marina areas. The path is mostly paved and flat, running past Lynde Shores, Whitby Harbour, Iroquois Beach, and the waterfront promenade, with plenty of spots to stop for views of the lake. Boardwalk sections, shaded pockets, and signed wayfinding make it simple to follow, and it connects seamlessly to the rest of the Great Lakes Waterfront Trail. A scenic, reliable lakeside route ideal for relaxed rides, long walks, or sunrise outings by the water.

The main trail at Cullen Central Park winds through a mix of forest, meadow, and wetland, following sections of Lynde Creek and connecting several quiet natural pockets across the park. The route is a blend of paved and packed-earth paths, with boardwalks in wetter areas and shaded stretches that feel surprisingly peaceful for an in-town trail. Multiple access points make it easy to do short loops or longer walks that link into the wider Lynde Creek corridor. A calm, scenic everyday trail and one of Whitby’s best spots for relaxed nature time.

Once the site of Cullen Gardens, Cullen Central Park is now a large green space with forested walking trails, open meadows, wetlands, and quiet connectors that follow Lynde Creek through the property. The paved and natural-surface paths make it easy to explore on foot or by bike, with shaded sections, small bridges, and plenty of wildlife activity around the creek. It’s a versatile everyday park — part nature reserve, part community space — and one of Whitby’s most popular spots for relaxed walks, family outings, and access to the wider Lynde Creek trail network.

Whitby Harbour is a historic and important port on Lake Ontario. It is known for its sheltered basin, which facilitated regional trade, particularly grain exports, in its early history. Today, it is a central hub of the town of Whitby, serving both commercial and recreational purposes. The marina offers over 300 berths and is home to the Whitby Yacht Club.
