Outdoor Activities & Natural Spaces in Markham — May
May is the best month to explore Markham's exceptional green spaces. The trails are clear, the foliage is emerging, and the city's parks are at their most beautiful. These are the outdoor experiences that define what it means to live in Markham.
Canada's first national urban park borders Markham's eastern edge, offering over 100km of trails through forests, wetlands, and river valleys. The Orchard Trail, Glen Eagles Trail, and Rouge River Heritage Trail are at their most spectacular in May. Free to access year-round — bring proper footwear for spring conditions.
Milne Dam's riverside trails along the Rouge River are among Markham's most beloved outdoor destinations. In May, the park is alive with migratory birds, spring wildflowers, and active wildlife. The dam viewpoint is a highlight. Leashed dogs welcome. Free parking on weekends.
Markham's dedicated cycling infrastructure connects major neighbourhoods along the Rouge River corridor, through Unionville, Cornell, and towards the Stouffville trail system. The Markham Cycling Map (available at City of Markham community centres) shows the full network of bike lanes and off-road paths open in May.
One of Canada's top-rated golf courses opens its spring season in May. Angus Glen — host of multiple Canadian Opens — is the GTA's most prestigious public golf experience.

May brings Unionville's heritage Main Street to life — patios open, the Victorian streetscape is in full bloom, and the restaurants, boutiques, and galleries that make Unionville one of the GTA's most celebrated destinations are at their most inviting. The Toogood Pond walk behind Main Street is a Markham May essential.
